The Game of Thrones castle that’s also been a real royal home for 1,000 years

Most castles feel frozen in time. Roped off. Preserved. Silent. The Alcázar of Seville feels alive — because it is. Walk through its gates today and you are stepping into a building that has been continuously occupied for over a thousand years, and where the Spanish royal family still sleeps when they visit the city.

That alone would make it extraordinary. But the Alcázar is much more than a royal address. It is one of the most beautiful buildings on earth.

Built by kings who changed everything

The Alcázar’s story begins in the 10th century, when Moorish rulers built a palace-fortress on this site above the Guadalquivir River. Over the following centuries, every ruler who took Seville added to it, rebuilt parts of it, or stamped their own ambitions onto its walls.

The building you see today is largely the creation of one king: Pedro I of Castile, who commissioned a sweeping rebuild in the 14th century. He hired artisans from Granada and Toledo — Muslim craftsmen working for a Christian king — and the result was Mudéjar architecture at its absolute peak. Horseshoe arches. Geometric tilework. Carved plasterwork so intricate it looks like lace. Ceilings that seem to float.

Christopher Columbus was received here before his voyages to the Americas. Royal weddings happened in its courtyards. The Alcázar has not sat on the sidelines of history — it has been at the centre of it.

Why Game of Thrones chose this place

When the production team behind Game of Thrones needed somewhere to represent the Water Gardens of Dorne — sun-drenched, exotic, unlike anything else in Westeros — they came here.

The gardens of the Alcázar appeared in Seasons 5 and 6 as the seat of House Martell. The fountains, the orange trees, the long reflecting pools surrounded by Moorish stonework — it is cinematic before a camera is even pointed at it.

Visitors today walk the same paths where those Dornish scenes were filmed. The Alcázar was a UNESCO World Heritage Site from 1987, recognised alongside Seville’s great cathedral as one of the most significant historic complexes in the world.

The rooms that stop you cold

The upper floors of the Alcázar remain a private royal residence — the Spanish royal family uses them when visiting Seville for official business. What visitors can access is, frankly, enough.

The Patio de las Doncellas — the Courtyard of the Maidens — is probably the most photographed space in the building. A long, shallow reflecting pool runs down its centre, flanked by delicate arched galleries. The stillness of the water. The symmetry of the stonework. It demands you stop moving.

The Salón de los Embajadores — the Hall of the Ambassadors — is where Pedro I held court. Its gilded dome, encrusted with stars and geometric patterns, rises above you like something from a dream. This was where power was performed in the 14th century, and it still feels like it.

The Alcázar holds its own against anything on the continent. See Europe’s most magnificent royal palaces for the full picture — its thousand-year continuity as a working royal residence is matched by almost nothing else.

The gardens: where you lose track of time

Many visitors underestimate the gardens. They cover nearly five hectares and have been planted, redesigned, and replanted across centuries. Orange trees line straight paths. Fountains mark the centres of formal pools. Pavilions from different eras stand between the hedges.

Come in spring and the scent from the orange blossom can stop you mid-step. Come in summer and the shade of the garden groves offers something the rest of Seville cannot: genuine cool. The gardens are included in the entrance ticket. Give them at least an hour.

Practical: how to visit the Alcázar

The Alcázar is open year-round, with morning sessions beginning at 09:30. Tickets are best booked in advance — it is one of the most visited sites in Spain, and queues without a booking can be long. Entrance costs approximately 14.50 euros for adults.

The early morning slot is the one to choose. By 10:30, the Patio de las Doncellas fills with tour groups and the quiet magic is harder to find. Arrive at opening, move through the palace first, then take your time in the gardens as the crowds build behind you.

If you are planning a wider trip, Spain’s full range of remarkable castles extends far beyond Seville — from the Alhambra in Granada to barely-visited hilltop strongholds in Aragon.

Frequently asked questions

Is the Alcázar of Seville still a royal residence?

Yes. The upper floors of the Alcázar are the official residence of the Spanish royal family when they visit Seville. This makes it one of the oldest royal palaces in the world still in active use. The areas open to the public include the lower palace rooms, the historic halls, and the gardens.

Was Game of Thrones really filmed at the Alcázar of Seville?

Yes. The gardens and exterior spaces of the Alcázar served as the Water Gardens of Dorne in Seasons 5 and 6 of Game of Thrones. The building’s distinctive Moorish architecture made it the ideal stand-in for the southern Westerosi kingdom of House Martell.

How long should I spend at the Alcázar?

Allow at least two to three hours — one for the palace interior, and one to two for the gardens. If you are deeply interested in the architecture or history, you could easily spend four hours. The site is large and its details reward a slow pace.

What is the best time to visit the Alcázar of Seville?

Early morning — the first session at 09:30 — is the best time to visit. The palace is quieter, the light in the courtyards is beautiful, and you can move through the key rooms before the main crowds arrive. Avoid midday visits in summer, when the palace is very busy and Seville’s heat is intense.
