01 Tower of Hercules
Torre de Hércules
Spain · 6.3 km from A Coruña43.386° N 8.406° W
- UNESCO World Heritage
Luis Miguel Bugallo Sánchez (Lmbuga) · CC BY-SA 3.0 There were dozens of lighthouses like this one once, scattered around the edges of the Roman world. There is exactly one left that still works.
Did you know? The 18th-century restoration was carried out by the naval engineer Eustaquio Giannini, and UNESCO later singled it out as exemplary for protecting the Roman core.
02 Cave of Altamira
Cueva de Altamira
Spain · 25.7 km from Santander43.383° N 4.117° W
- UNESCO World Heritage
Image by janeb13 from Pixabay The Cave of Altamira, near Santillana del Mar in Cantabria, holds some of the finest Palaeolithic art in the world, and no other cave in northern Spain has such complex and crowded painting. The cave is about 270 m long, a series of passages in the limestone of Mount Vispieres.
03 León Cathedral
Catedral de Santa María de Regla de León
Spain · 2.2 km from León42.599° N 5.567° W
- UNESCO World Heritage
Image by TerapiasNaturales from Pixabay León's cathedral, Santa María de Regla, is the Spanish cathedral that went furthest in the Gothic dream of replacing walls with light. It has around 125 windows and about 1,800 square metres of stained glass, most of it made between the thirteenth and fifteenth centuries, one of the largest collections of medieval glass anywhere.
Did you know? For centuries a dried hide over a door was said to be a mole that wrecked the builders' work by night; in the 1990s it proved a leatherback turtle shell.
04 Aljafería
Spain · 0.9 km from Zaragoza41.656° N 0.897° W
- UNESCO World Heritage
Image by Pixels4Free from Pixabay The Aljafería is the finest surviving building from the taifa kingdoms, the patchwork of Muslim states that followed the break-up of the Caliphate of Córdoba. It was raised in Zaragoza for Ahmad al-Muqtadir of the Banu Hud dynasty and largely finished between 1065 and 1081.
Did you know? The palace's architect is known by name: a Slav called Zuhayr, recorded by a Zaragoza writer active in the late eleventh century.
05 Royal Alcázar of Seville
Spain · 2.5 km from Seville37.384° N 5.991° W
- UNESCO World Heritage
Image by Danor from Pixabay The Royal Alcázar of Seville is a palace built as a sequence of courtyards, each opening into the next: arcades carved with lace-like plaster, tiled walls, pools and channels of water, and beyond them a maze of gardens full of orange trees and palms.
Did you know? Arabic inscriptions in Pedro I's palace refer to the Christian king as 'Sultan Don Bidru'.
06 Palacio Episcopal de Astorga
Spain42.458° N 6.056° W
- UNESCO World Heritage
Elgamizzzz · CC BY-SA 4.0 In a small cathedral town of the Spanish meseta, Antoni Gaudí built a castle for a bishop. The Episcopal Palace of Astorga rises beside the cathedral like a building from a fairy tale: four round corner towers with pointed caps, a deep dry moat, a porch of three great flared arches and a skyline of pinnacles and chimneys, all in pale grey granite. It is one of only a handful of Gaudí buildings outside Catalonia.
Did you know? A fire destroyed the old episcopal palace of Astorga in 1886, prompting the commission to Gaudí.
07 Antequera Dolmens Site
Spain · 35.5 km from Málaga37.023° N 4.548° W
- UNESCO World Heritage
Image by ELG21 from Pixabay Nearly six thousand years ago, farming communities on the plain of Antequera in southern Spain raised one of the most ambitious stone monuments of prehistoric Europe. 5 metres long assembled from 32 enormous slabs, the heaviest weighing in the order of 150 tonnes, with a row of standing pillars down the middle to carry the roof, a solution almost unknown in other dolmens.
Did you know? The Antequera Dolmens Site was inscribed as a UNESCO World Heritage Site in 2016.
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.
