The Most Beautiful Castles, Palaces and Fortresses in the United Kingdom
24 places · updated 14 October 2026
In short: By our ranking, the most beautiful castles, palaces and fortresses in the United Kingdom are Tower of London, Tintagel Castle and St Michael's Mount. The list covers 24 castles, palaces and fortresses. Last updated 14 October 2026.
Britain's fortifications record nearly a thousand years of conquest and display. The Normans brought the stone keep after 1066, Edward I ringed north Wales with concentric castles, Scottish lords raised tower houses on crags and sea stacks, and by the Tudor age defence gave way to palaces built to impress. An island nation added its own chapter: forts, harbours and warships that guarded the coast rather than the border.
At the heart of London the Tower of London keeps its White Tower, begun under William the Conqueror, and the Crown Jewels. Far to the west, Tintagel's ruins cling to a Cornish headland bound up with Arthurian legend, while St Michael's Mount rises from the sea and is reached on foot only when the tide uncovers its causeway. HMS Victory, Nelson's flagship at Trafalgar, sits in dry dock at Portsmouth, and Hampton Court Palace shows the Tudor court of Cardinal Wolsey and Henry VIII in red brick.
Scotland brings the most dramatic settings: Eilean Donan on its island where three sea lochs meet, Dunnottar's ruins on a cliff-girt rock near Stonehaven, Urquhart above the dark water of Loch Ness, and Caerlaverock with its rare triangular plan inside a moat. In the south of England, Bodiam stands four-square in its own lake, the image of a late medieval castle.

01 Tower of London
United Kingdom · 3 km from London51.508° N 0.076° W
- UNESCO World Heritage
Matthias Bethke · CC BY-SA 4.0 Around the keep, later kings wrapped two concentric rings of walls and a moat. Richard I doubled the enclosure, Henry III added the north and east walls with their towers, and Edward I completed the outer ward in 1285, fixing the plan that survives today.
Did you know? In 1671 Colonel Thomas Blood bound the Jewel House keeper and seized the crown, sceptre and orb, foiled only when the keeper's son arrived.
02 Tintagel Castle
United Kingdom50.668° N 4.761° W
Rawac · CC BY-SA 3.0 The island was important long before any castle. Between about 450 and 600 it was a high-status settlement, probably a seasonal seat of the rulers of Dumnonia, and excavations have turned up more imported Mediterranean pottery – amphorae and fine red tableware – than any other site of that period in Britain or Ireland; digs in 2016–17 uncovered the outlines of buildings of the 5th or 6th century and a slate bearing writing.
Did you know? Richard of Cornwall got the headland in 1225 by trading away the manor of Merthen for it.
03 St Michael's Mount
United Kingdom · 5.5 km from Penzance50.117° N 5.478° W
Image by LeeChandler from Pixabay The Cornish name, Karrek Loos yn Koos, means "the grey rock in a wood", and may preserve a memory of the forest that once covered the bay before the sea rose over it, roughly around 1700 BC. Local tradition holds that in 495 fishermen saw the Archangel Michael standing on a ledge of the rock, and from the 12th century the island was a Benedictine priory linked to Mont-Saint-Michel in Normandy, its twin across the Channel.
Did you know? The Mount is one of several candidates for Ictis, the tin-trading island described by the Greek historian Diodorus Siculus in the 1st century BC.
04 Hampton Court Palace
United Kingdom · 18.8 km from London51.403° N 0.337° W
Image by LaraHughes from Pixabay Wolsey's work survives in the Base Court and the gatehouse to the Clock Court, where relief busts of Roman emperors by the Italian sculptor Giovanni da Maiano are set into the brickwork.
Did you know? In 1986 a fire, thought to have been started by a candle in a grace-and-favour apartment, gutted part of the King's Apartments; restoration took until 1990.
05 Bamburgh Castle
United Kingdom55.609° N 1.711° W
Image by 18623647 from Pixabay Before the stone castle there was a royal fortress. A Brittonic stronghold known as Din Guarie may have stood here in the 5th and 6th centuries; in 547 the Anglian king Ida took it, and around 600 it was named Bebbanburg after Bebba, wife of King Æthelfrith. For a time this was a seat of the kings of Northumbria.
Did you know? Brian Hope-Taylor's digs of the 1960s also produced the Bamburgh Beast, an early medieval gold plaque that gave its name to the castle's best-known find.
06 Windsor Castle
United Kingdom · 26.1 km from Reading51.484° N 0.604° W
Image by diego_torres from Pixabay The silhouette most people know is surprisingly young. Under George IV, from 1824, the architect Jeffry Wyatville reworked the Upper Ward into a romantic Gothic fantasy and raised the Round Tower by about thirty feet so that it would dominate the skyline, at a cost that ran past a million pounds by 1840.
Did you know? King John used Windsor as his base during the negotiations that led to the sealing of Magna Carta at nearby Runnymede in 1215.
07 Eilean Donan Castle
United Kingdom57.274° N 5.516° W
Image by rzierik from Pixabay The island takes its name from Donnán of Eigg, a Celtic saint martyred in 617. A fortified castle was first built in the 13th century, in the reign of Alexander II, and over the following centuries it grew and shrank as a stronghold of the Clan Mackenzie and their allies, the MacRaes.
Did you know? The only drawing of the castle before 1719, made in 1714, was rediscovered when rebuilding was almost complete, so today's details differ from the original.
08 Dunnottar Castle
United Kingdom · 22.9 km from Aberdeen56.946° N 2.197° W
Image by Collie581 from Pixabay The site may have been fortified in the early Middle Ages: the Annals of Ulster record sieges of Dún Foither in 681 and 694, and Scottish chronicles place the death of King Donald II here during a Viking attack in 900, although archaeologists have not proved that the early fort stood on this exact headland. The buildings seen now date mostly from the 14th to the 17th centuries.
Did you know? William Keith was excommunicated for raising his tower on consecrated church ground, and needed a papal bull in 1395 to have the sentence lifted.
09 Caerlaverock Castle
United Kingdom · 10.3 km from Dumfries54.976° N 3.524° W
DeFacto · CC BY-SA 4.0 The Maxwell family held these lands from about 1220, when Alexander II granted them to Sir John Maxwell. His first castle, square and among the earliest stone castles in Scotland, was abandoned for a rock outcrop some 200 metres to the north, where his brother Sir Aymer began the present building; it was finished in the 1270s. In July 1300 Edward I of England arrived with a large army that included eighty-seven English barons.
Did you know? During the Wars of Independence Sir Eustace Maxwell dismantled his own castle so the English could not use it, and Robert the Bruce rewarded him.
10 Urquhart Castle
United Kingdom · 20.3 km from Inverness57.324° N 4.442° W
Image by Maikiua from Pixabay The castle itself goes back to the thirteenth century, when Alexander II granted the lands to Thomas de Lundin and a first stronghold was raised on the motte at the south-west end of the site. It enters written history in 1296, when Edward I of England captured it at the start of the Wars of Scottish Independence, and in 1307 Robert the Bruce took it back as a royal fortress.
Did you know? According to Adomnán's Life of Columba, the saint converted a Pictish nobleman named Emchath and his household in this area in the late sixth century.
11 Bodiam Castle
United Kingdom51.002° N 0.544° E
Image by diego_torres from Pixabay Bodiam has no keep. Its living quarters were built against the inside of the outer walls around a central courtyard, with four round corner towers, square towers in the middle of three sides and the main gatehouse on the fourth. The gatehouse, with machicolations, murder holes and gun loops, is the most strongly defended part.
Did you know? Dalyngrigge served as Captain of Brest in 1386–87, so he was probably abroad for the first years of building, and he was dead by 1395.
12 Edinburgh Castle
United Kingdom · 1.1 km from Edinburgh55.949° N 3.201° W
Image by Walkerssk from Pixabay What survives on the summit is a layered record of who needed it and why. The oldest roof on the rock covers St Margaret's Chapel, a tiny Romanesque room from the reign of David I in the twelfth century, one of the very few buildings of that age left in any Scottish castle. Around it come the Royal Palace, begun in the fifteenth century, and the Great Hall of the early 1500s with its hammerbeam roof.
Did you know? Imprisoned in 1479, the Duke of Albany escaped by getting his guards drunk and lowering himself from a window on a rope.
13 Conwy Town Walls
United Kingdom53.281° N 3.831° W
- UNESCO World Heritage
David Dixon · CC BY-SA 2.0 Many details reward a close look. The towers are open at the back, spanned originally by removable timber bridges, so that any stretch of wall could be cut off if an enemy got onto it. The Upper Gate keeps a rare surviving barbican. Along the southern wall, a unique row of twelve medieval latrines, built for the royal staff, projects from the parapet — a rare glimpse of everyday life in the Edwardian town.
Did you know? Medieval records say the walls were 'daubed', which suggests they may originally have been whitewashed rather than left as bare stone.
14 Castle Stalker
United Kingdom · 32 km from Fort William56.572° N 5.386° W
Ymblanter · CC BY-SA 4.0 A first fort on the site is thought to have been built around 1320 by the MacDougalls, Lords of Lorn. The Stewarts of Appin, who took over the lordship later in the fourteenth century, rebuilt it in its present form in the 1440s, and the castle is considered one of the best-preserved medieval tower houses in the west of Scotland.
Did you know? Beyond Monty Python it has appeared in Highlander: Endgame, the Netflix series Sense8 and the Black Mirror episode Loch Henry.
15 Corfe Castle
United Kingdom · 15 km from Bournemouth50.640° N 2.059° W
Image by brendan347 from Pixabay The first castle here was raised by William the Conqueror soon after the Norman Conquest of 1066. Under Henry I a great stone keep was begun around the end of the eleventh century and finished by 1105, built of the local Purbeck limestone. The site already carried a darker story: tradition places the murder of the young king Edward the Martyr here in 978, before the castle existed in its present form.
Did you know? King John and Henry III kept Eleanor, Fair Maid of Brittany, a rival claimant to the throne, confined at Corfe until 1222.
16 Caernarfon Castle
United Kingdom53.139° N 4.277° W
- UNESCO World Heritage
Tilman2007 · CC BY-SA 4.0 Work on the stone castle began in 1283, right after Edward's conquest of Gwynedd, on the site of a Norman motte-and-bailey from the late eleventh century. The master mason was probably James of Saint George, the engineer behind Edward's Welsh castle programme, although some historians credit Walter of Hereford, who took charge of the second phase.
Did you know? The tale that Edward I promised the Welsh a prince who spoke no English, then showed them his baby son, can only be traced to the 16th century.
17 Leeds Castle
United Kingdom · 34.1 km from Southend-on-Sea51.249° N 0.630° E
Worldfootage · CC BY-SA 4.0 Tradition traces the site back to 857, when a Saxon chief named Led or Leed is said to have built a wooden hall on two islands in the river. In 1119 Robert de Crevecoeur replaced it with a Norman stronghold in stone. In 1278 it passed to Eleanor of Castile, Edward I's queen. Edward strengthened its defences and added a barbican spanning three islands, along with a gloriette, a compact block of royal apartments.
Did you know? A sundial at the castle tells the time in Belvoir, Virginia, the Fairfax home, and a matching sundial stands in America.
18 Royal Pavilion
United Kingdom · 2.4 km from Brighton50.822° N 0.138° W
Image by Shirley810 from Pixabay Between 1815 and 1822, architect John Nash tore into Holland's discreet villa and rebuilt it as something closer to a fantasy of Mughal India transplanted onto the English south coast: bulbous onion domes, minarets topped with chhatris, cusped arches, all in a style historians now call Indo-Saracenic, an invented British idiom that borrowed the silhouette of South Asian and Islamic architecture without much concern for which tradition any…
Did you know? When Brighton bought the building, the royal household stripped out most of its fittings for Buckingham Palace and Windsor; Victoria later sent many unused pieces back.
19 Conwy Castle
United Kingdom53.280° N 3.826° W
- UNESCO World Heritage
Image by stevenm-s from Pixabay The castle was built for Edward I of England during his conquest of Wales. He took the site in 1283, moved the Cistercian abbey that stood there further up the valley, and in its place founded an English garrison town. Work began within days. Under the direction of Master James of St George, the king's master builder from Savoy, the castle went up in just four years, from 1283 to 1287, with the town walls built alongside.
Did you know? Edward I was besieged at Conwy by Welsh rebels in the winter of 1294–95 and was supplied only by sea.
20 Dunluce Castle
United Kingdom55.211° N 6.579° W
Image by hhach from Pixabay The first castle was built in the thirteenth century by Richard de Burgh, the Earl of Ulster. By the early 1500s it was held by the McQuillans, and in 1584 it was seized by Sorley Boy MacDonnell, whose clan made it their chief seat in Antrim and remodelled it in a Scottish manner.
Did you know? The planned town next to the castle was built around 1608, before the official Plantation of Ulster, and was razed in the 1641 uprising.
21 Kilchurn Castle
United Kingdom56.404° N 5.027° W
Steve Partridge · CC BY-SA 2.0 The castle was begun around 1450 by Sir Colin Campbell, first laird of Glenorchy, founder of what became the most powerful branch of Clan Campbell in the central Highlands. His five-storey tower house is still the core of the site, and for about a century and a half Kilchurn was the family's headquarters.
Did you know? Sir Duncan Campbell, known as Black Duncan, rebuilt the south range in 1614 and added a range with a chapel.
22 Harlech Castle
United Kingdom52.860° N 4.109° W
- UNESCO World Heritage
Image by diego_torres from Pixabay Edward I ordered it in 1283, in the wake of his campaign against the last native princes of Wales, and it was largely finished by the end of 1289 at a cost of about £8,190. The work was directed by Master James of St George, the military engineer from Savoy who also built the king's castles at Conwy, Caernarfon and Beaumaris; the round-headed doorways and other details at Harlech echo buildings in his homeland.
Did you know? A Lancastrian garrison held Harlech from 1461 to 1468, a siege traditionally credited with inspiring the song "Men of Harlech".
23 Cardiff Castle
United Kingdom · 0.9 km from Cardiff51.482° N 3.181° W
User: (WT-shared) Cardiff at wts wikivoyage · Public domain After the Normans pushed into South Wales in the late 11th century they raised a tall earth motte inside the old Roman walls, and in the following century crowned it with the many-sided stone shell keep that still stands on its mound, ringed by a moat.
Did you know? The Arab Room is known for its gilded honeycomb ceiling.
24 Craigievar Castle
United Kingdom · 37.2 km from Aberdeen57.174° N 2.718° W
Anais Culot · CC BY-SA 4.0 The tower was begun by the Mortimer family, who ran out of money before it was finished. In 1610 the unfinished house was bought by William Forbes, an Aberdeen merchant who had grown rich trading with the Baltic ports and was known as "Danzig Willie". He completed it around 1626, and his decisions shaped everything that makes the castle remarkable.
Did you know? The entrance door is still protected by a massive iron yett, the lattice gate typical of Scottish tower houses.
How this list is ranked
Places are chosen for how they look, not for how famous they are: each one has its own description and a photograph credited to its author. The order is a single world ranking that weighs the beauty of the place in curated photography together with how widely it is documented — the number of language editions of its encyclopedia article and how often that article is read in a year. The list is rebuilt as places are added, so the order and the counts on this page are always current.
