Spain: Ten Attractions and Natural Wonders
A cathedral still under construction after more than 140 years, a Moorish palace complex regarded as one of the finest surviving examples of Islamic architecture in Europe, and a mysterious rock island said to have inspired the myth of Atlantis

Layers of Moorish, Christian, and modern Spain
Spain's history as a crossroads between Europe and the Islamic world has left behind an architectural record found almost nowhere else — Moorish palaces and mosque-cathedrals standing alongside Gothic cathedrals and, in Barcelona, some of the most singular modern architecture anywhere on earth. Add centuries-old pilgrimage routes, Mediterranean nightlife culture, and some genuinely strange natural landmarks, and Spain offers one of the widest ranges of sightseeing in Europe within a single country.
The eight below run from Barcelona and Madrid to Andalusia, the Camino de Santiago, and the Balearic Islands. Spring and autumn generally offer the most comfortable weather for sightseeing across the country.
1. The Sagrada Família
The Sagrada Família, Antoni Gaudí's unfinished masterwork, has been under construction in Barcelona since 1882 and remains incomplete, funded entirely by donations and ticket sales rather than public money — a completion date sometime in the coming years has been targeted for decades, though the building's scale and intricacy keep pushing it back. Its combination of Gothic structure and organic, nature-inspired Art Nouveau detail makes it unlike any other cathedral in the world.
2. The Alhambra
The Alhambra, a sprawling Moorish palace and fortress complex overlooking Granada, represents the pinnacle of Islamic architecture in Spain, its courtyards, carved stucco, and reflecting pools built for the emirs of the Nasrid dynasty before the city fell to Christian forces in 1492. It remains one of the most visited monuments in Spain, with timed-entry tickets required well in advance given permanently high demand.
3. Park Güell
Park Güell, another Gaudí creation, transforms a public park into a whimsical landscape of mosaic-tiled benches, curved stonework mimicking natural forms, and a gingerbread-house-like entrance pavilion — originally conceived as an upscale garden city that failed commercially but succeeded brilliantly as public art, and now a UNESCO World Heritage Site alongside several other Gaudí works across Barcelona.
4. Madrid's Plaza Mayor
Madrid's Plaza Mayor, completed in the early 17th century, has served across its history as a marketplace, bullfighting arena, and site of public executions during the Spanish Inquisition — a weighty history now given over to cafés, street performers, and the city's ordinary daily life. It sits within walking distance of the Prado Museum, one of the world's foremost art collections.
5. The Camino de Santiago
The Camino de Santiago, a network of pilgrimage routes converging on the cathedral of Santiago de Compostela in Galicia, has drawn Christian pilgrims since the Middle Ages and now attracts a broader mix of religious pilgrims, hikers, and travellers seeking a long-distance walking challenge. Routes can take anywhere from a week to over a month depending on the starting point chosen.
6. Seville's Plaza de España
Plaza de España, built for Seville's 1929 Ibero-American Exposition, forms a grand semicircular plaza with a canal that can be crossed by small rowboats and a series of ornately tiled alcoves representing each Spanish province — an ambitious architectural showpiece that has since appeared in numerous films, including as a stand-in for other planets and palaces.
7. The Mezquita of Córdoba
The Mezquita of Córdoba, begun as a mosque in 785 AD under Moorish rule and converted into a cathedral after the Christian reconquest, holds a forest of over 850 columns supporting distinctive red-and-white striped double arches — an architectural hybrid unlike anything else in Europe, and a UNESCO World Heritage Site reflecting the layered religious history of Andalusia.
8. Es Vedrà, Ibiza
Es Vedrà, a dramatic rocky islet off Ibiza's southwest coast, has long attracted myth and legend, from claims of unusual magnetic properties to theories linking it to the lost city of Atlantis — while Ibiza itself is better known internationally for its nightlife and electronic music scene, this quieter, almost mystical corner of the island offers a striking natural counterpoint.
9. Toledo
Toledo, Spain's capital before Madrid and known historically as the "City of Three Cultures" for the Christian, Muslim, and Jewish communities that shaped it side by side for centuries, sits on a hilltop almost encircled by a gorge of the Tagus River. Its skyline of church towers, a Gothic cathedral, and the Alcázar fortress is largely unchanged since the 16th century, when El Greco painted the city he adopted as home.
An easy half-day trip from Madrid by high-speed train, Toledo's steep, narrow streets reward at least an overnight stay once the day-trippers leave.
10. Teide National Park, Tenerife
Mount Teide, on the Canary Island of Tenerife, is Spain's highest peak and, measured from the seabed, one of the tallest volcanoes on Earth — a UNESCO World Heritage Site whose barren, Mars-like crater floor of solidified lava fields feels closer to another planet than to Europe. A cable car climbs to near the summit, and the park's clear, high-altitude skies make it one of the world's premier stargazing sites.
The volcano last erupted in 1909 and remains active, monitored alongside its dramatic, otherworldly scenery.
Spain rewards a trip of two weeks or more given its scale: Barcelona and Madrid can each fill several days on their own, with Andalusia (Granada, Córdoba, Seville) forming a natural southern extension for those with additional time.
