Aiete Palace: history, gardens and secrets of San Sebastián’s aristocratic retreat

If you venture a little way out of the centre of San Sebastián, you will find a corner where time seems to slow down. The Aiete Palace, with its romantic gardens and stately architecture, isn’t featured on all the postcards… but it should be. It was once a royal residence and a diplomatic venue, and today it’s a green space open to everyone, where history and nature go hand in hand. It’s ideal for those who want to explore the city beyond the usual tourist spots, especially if you’re travelling by rental bike and want to get away from the crowds without any hassle.

Where is the Aiete Palace and what is it?

The Aiete Palace is located in the Aiete neighbourhood, a quiet residential area less than 15 minutes by bike from the city centre. Surrounded by a huge, leafy park, this 19th-century building looks like something out of an English fairy tale.

It’s not just a beautiful house: it’s one of the city’s most interesting cultural spaces, with exhibitions, a library and activities open to the public all year round. And yes, admission is free.

History of Aiete Palace: from royal residence to cultural centre

This mansion was built in 1878 on behalf of the Dukes of Bailén, but it was royalty who made it famous. Alfonso XIII and Queen María Cristina spent their summers here, and years later, dictators such as Franco also did so, using it as a summer residence for decades.

Once democracy was established, the building was transformed into what it is today: a cultural centre with a memory, which also houses the House of Peace and Human Rights, a symbol of the changing times.

Walking through its corridors is not just about looking at walls, it is about exploring fragments of Spain’s recent history.

What to see at Aiete Palace and its gardens

• The main building: with its classic façade, marble staircases and high ceilings, it maintains an aristocratic yet welcoming atmosphere.
• Temporary exhibitions: focusing on human rights, history and contemporary art.
• The library, which is very well stocked and has ideal reading corners if you like to travel at a leisurely pace.

But if there’s one thing that takes the cake, it’s the palace gardens. Over 70,000 m² of paths, ponds, centuries-old trees and shaded areas. There’s even an artificial grotto and a small pond with ducks. If you go by bike, you can park right at the entrance and then lose yourself among the trees and benches with views.

Interesting facts that only locals can tell you

• In the 1940s, Franco received international leaders here, while the city surrounded him with uncomfortable silence.
• There is a tree planted by Mikhail Gorbachev as a symbol of reconciliation.
• The park was designed in the English style, but it has areas that imitate French gardens, so it’s like taking a mini European tour without leaving Donosti.
• If you visit first thing in the morning, you’ll see locals practising tai chi or jogging among the statues.

A tip: bring something to snack on. There are perfect picnic areas under the shade with birds singing in the background.
