The Most Remarkable Hillforts in the World
11 places in 4 countries · updated 14 October 2026
In short: By our ranking, the most remarkable hillforts in the world are Dún Aonghasa (Ireland), Pskov Krom (Russia) and Maiden Castle, Dorset (United Kingdom). The list covers 11 hillforts in 4 countries. The United Kingdom has the most, with 5. Last updated 14 October 2026.
A hillfort turns a natural height into a fortress: ramparts and ditches follow the contour of a summit or a cliff edge, so that the shape of the defences is the shape of the land. The most striking ones are legible from a distance as rings of earth or stone wrapped around a hill, and from within they command wide views over valleys, coasts and routes. Many date from the Bronze and Iron Ages, but the idea of the fortified height carried on into medieval citadels that still crown their cities.
Dún Aonghasa on Inis Mór in the Aran Islands is a semicircle of drystone walls ending at a sheer sea cliff. The Castro of Baroña in Galicia packs round stone houses onto a rocky headland over the Atlantic. Maiden Castle in Dorset is one of the largest Iron Age hillforts in Britain, its multiple ramparts folding around a long ridge, and Tre'r Ceiri on the Llŷn Peninsula keeps the stone hut circles of a hilltop settlement. The same logic of the defended hill underlies Prague Castle above the Vltava and the white-walled Kazan Kremlin over the Kazanka and the Volga.
The forts on this list are chosen for how they look and arranged by beauty. Each has its own text, a photograph with the author named and a location on the map, and the section can be browsed country by country on separate pages.

01 Dún Aonghasa
Dun Aengus
Ireland53.126° N 9.766° W
Fried Marek · CC BY 4.0 Dún Aonghasa sits on the very lip of the Atlantic, on the southern cliffs of Inis Mór, the largest of the Aran Islands. The cliff below it drops close to ninety metres straight into the ocean, and the fort's innermost enclosure is a semicircle that simply stops at the edge, as if the sea had taken the rest. That is probably what happened: the original plan was most likely oval or D-shaped, and part of the fort has since fallen with the rock beneath it. Few prehistoric monuments anywhere are staged so dramatically.
Did you know? Excavations led by Claire Cotter between 1992 and 1995 found the remains of round huts from the fort's first Bronze Age settlement.
02 Pskov Krom
Russia · 1 km from Pskov57.821° N 28.329° E
Alexxx1979 · CC BY-SA 4.0 The Pskov Krom is the kremlin at the very origin of the city: a narrow, high promontory where the Pskova River flows into the Velikaya, fortified since at least the 8th century and first named in the chronicles as the "Krom" in 1113. The ensemble covers the Krom itself, about 3.5 hectares, and the adjoining Dovmont's Town, about 1.5 hectares, named after the 13th-century prince who walled it. In the days of the Pskov Republic, from the 14th to the early 16th century, this was the political and spiritual core of the land: the veche assembly met on the square beside the cathedral, next to the kremlin's storehouses.
03 Maiden Castle, Dorset
Maiden Castle
United Kingdom50.695° N 2.470° W
Hadrianus1959 · CC BY-SA 4.0 Maiden Castle is the largest hillfort in Britain and one of the largest in Europe, a whole hilltop southwest of Dorchester wrapped in rings of grassy earthwork. At its greatest extent the enclosure covered about 19 hectares, an area English Heritage likens to fifty football pitches, and on the southern side the defences run to four banks and three ditches stacked one above the other. Walking the ramparts today, with sheep grazing in the ditches and the Dorset downs spread out on every side, the sheer scale of the labour is what strikes first: all of this was dug and heaped up by hand.
Did you know? Among the burials Wheeler excavated, one man had the iron bolt of a Roman catapult lodged in his spine.
04 Castro of Baroña
Castro de Baroña
Spain42.695° N 9.032° W
Image by rperucho from Pixabay The Castro de Baroña is an Iron Age hillfort set on a small rocky peninsula on the Atlantic coast of Galicia, in the parish of Baroña in the municipality of Porto do Son. The site was lived in from roughly the 1st century BC to the 1st century AD, and its position is the first thing that strikes a visitor: a knot of granite rock almost cut off by the sea, with the ocean breaking on three sides and only a thin neck of land tying it to the shore.
Did you know? Fragments of amphorae found at the site may be Punic, hinting that Mediterranean goods reached this remote Atlantic headland.
05 Qazan Kremlin
Russia · 5.2 km from Kazan55.797° N 49.107° E
- UNESCO World Heritage
Image by 6649312 from Pixabay The white-walled citadel of Kazan is where two worlds meet. It stands on the site of the fortress of the Kazan khans, which Ivan the Terrible's army captured in 1552; the tsar then had it rebuilt in stone by Pskov masters Postnik Yakovlev and Ivan Shiryay, known as Barma. Their Annunciation Cathedral, built between 1554 and 1562 from local pale sandstone rather than brick, is the oldest building inside. The walls and towers themselves date from the 16th and 17th centuries, with later renovations, and the Spasskaya Tower at the southern end still serves as the main gate.
Did you know? Postnik Yakovlev and Barma, the Pskov masters who rebuilt the kremlin in stone, are the same builders credited with St Basil's Cathedral in Moscow.
06 Kremlin
Russia · 0.4 km from Moscow55.752° N 37.618° E
- UNESCO World Heritage
Image by dondelord from Pixabay The Moscow Kremlin is a walled citadel on Borovitsky Hill, where the Neglinnaya once flowed into the Moskva River. It has been the seat of Russian power, with interruptions, for most of the last seven centuries. A timber fort stood here in the 12th century. Ivan I rebuilt it in oak in 1339, and Dmitry Donskoy replaced that with white limestone in the 1360s. The red-brick walls and towers seen today date from 1485–1495. They were built for Ivan III by Italian engineers, above all Pietro Antonio Solari, whose name is still carved in Latin over the Spassky Gate. The wall runs for about 2.2 km around an irregular triangle, between 5 and 19 metres high depending on the ground, and has twenty towers. The tallest, the Troitskaya, reaches 80 metres. The illuminated stars on several towers replaced golden eagles in Soviet times.
Did you know? The 202-tonne Tsar Bell has never rung: water thrown on it during a 1737 fire cracked it and broke off a slab weighing over 10 tonnes.
07 Grianán of Aileach
Grianan of Aileach
Ireland · 6.7 km from Londonderry/Derry55.017° N 7.433° W
Gareth Wray · CC BY-SA 4.0 The Grianán of Aileach sits on the top of Greenan Mountain, only 244 metres high but placed so that it commands the land between Lough Swilly and Lough Foyle, and on a clear day the view takes in parts of Donegal, Londonderry and Tyrone. The fort itself is a perfect ring of drystone: a wall roughly four and a half metres thick and five metres high encloses a grassy circle about 23 metres across. Inside, three terraces step up the face of the wall, linked by flights of stairs, so that you can walk right round the top of the rampart. Two narrow passages run within the thickness of the wall on either side of the lintelled entrance, stopping short for reasons no one has explained.
Did you know? Ptolemy's second-century map of Ireland marks a royal site that many scholars identify with Aileach, suggesting the hilltop was important long before the stone fort.
08 Uffington Castle
United Kingdom · 29.7 km from Oxford51.575° N 1.569° W
Steve Daniels · CC BY-SA 2.0 On the crown of Whitehorse Hill, at about 261 metres the highest ground in Oxfordshire, a great oval of grassy ramparts encloses roughly three hectares of chalk downland. Uffington Castle is one of the finest Iron Age hillforts in southern England, and it shares its hilltop with two of Britain's most haunting prehistoric landmarks: the stylised chalk horse galloping across the slope just below, and the flat-topped knoll of Dragon Hill. Together they form a single ancient landscape strung along the Ridgeway, the age-old track that follows the crest of the Berkshire Downs above the Vale of White Horse.
Did you know? Uffington Castle crowns Whitehorse Hill, which at about 261 metres is the highest point in Oxfordshire.
09 British Camp (Herefordshire Beacon)
British Camp
United Kingdom52.058° N 2.352° W
Image by AndaDeea from Pixabay British Camp crowns the Herefordshire Beacon, one of the summits of the Malvern Hills, and it is one of those places where the earthworks have become the shape of the hill itself. Ditch above ditch and bank above bank ring the summit, so that seen from the road below the hilltop rises in neat, grassy tiers; walkers have long compared it to a giant wedding cake. The summit stands at about 338 metres, and the diarist John Evelyn, writing in the 17th century, counted the prospect from here among the finest in England.
Did you know? Elgar's cantata Caractacus, first performed in 1898, began with his mother's suggestion that he write a tale about the Herefordshire Beacon.
10 Hambledon Hill
United Kingdom · 30.5 km from Bournemouth50.914° N 2.222° W
Tim Heaton · CC BY-SA 2.0 Hambledon Hill rises about 190 metres above the Blackmore Vale in north Dorset, a steep chalk outcrop on the south-western corner of Cranborne Chase, cut off from the Dorset Downs by the River Stour. From the valley below, its summit is visibly sculpted: two and in places three lines of ramparts wrap around the hilltop, following every contour, so that the whole hill looks carved rather than fortified. It is one of the best-preserved Iron Age hillforts in Britain, and from the top the view spreads across three counties, Dorset, Somerset and Wiltshire.
Did you know? A single grape pip and a fragment of vine leaf found in the Neolithic ditches have been read as possible evidence of early vine cultivation.
11 Tre'r Ceiri
United Kingdom52.975° N 4.424° W
Llywelyn2000 · CC BY-SA 4.0 Tre'r Ceiri, "the town of the giants" in Welsh, clings to the eastern summit of Yr Eifl, the three-peaked hill that rises straight out of the sea on the north coast of the Llŷn Peninsula. Well over 400 metres up, it is one of the highest hillforts in Britain, and one of the most complete: its drystone rampart still stands to about four metres in places, with the old wall-walk and gateways easy to follow. Later generations, finding a walled town of stone on a windswept mountaintop, could only imagine that giants had built it, and the name stuck.
Did you know? In 1903 the clergyman Sabine Baring-Gould, author of the hymn Onward, Christian Soldiers, helped clear 32 of the huts with Robert Burnard.
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.
