Motako Gaztelua-Castillo de la Mota

Motako Gaztelua – Castillo de la Mota, San Sebastián's hilltop fortress, crowns Mount Urgull in the Basque Country, standing 120 meters above the city. For centuries it guarded the harbor and the Old Town from seaborne attack, and today it ranks among the best viewpoints over the bay.

How old is the castle?

The first fortifications on Urgull date to 1194, when King Sancho VII "the Strong" of Navarre had the city enclosed with walls and a stronghold built to reinforce its defenses. Sancho VII himself later rebuilt and strengthened the fort, and Alfonso VIII of Castile carried out further improvements. In the 17th century, after lightning struck the castle, military engineer Tiburcio Spannocchi was brought in to reinforce the fortifications.

The fortress faced its harshest test in 1719, when a French army under the Duke of Berwick laid siege to San Sebastián, bombarding the castle for more than two weeks. The garrison held out under fire until a blaze broke out in the arsenal, finally forcing its defenders to surrender.

From military stronghold to city park

On August 25, 1921, San Sebastián's town council bought Mount Urgull from the Spanish army and turned the grounds into a public park open to residents and visitors. The fortress complex was declared a National Monument in 1925, and during the 1960s it underwent a major restoration before reopening as a cultural venue.

What will you see there?

A 24-meter Sacred Heart statue, erected above the castle chapel in 1950, towers over the fortress and is visible from nearly every corner of the city — one of San Sebastián's most recognizable landmarks. Inside the walls, the museum Casa de la Historia de Urgull traces more than 800 years of the city's past across several levels of the old stronghold. From the hilltop, views stretch over La Concha Bay, Ondarreta beach, and the rooftops of the Parte Vieja, San Sebastián's old quarter.

How do you get to the top?

The entrance to Mount Urgull sits right next to the Old Town, and footpaths wind up through the park past greenery and viewpoints until they reach the fortress at the summit. No special preparation is needed, though comfortable shoes help, since parts of the climb are steep. The park is freely accessible, making it a favorite spot for both tourists and locals out for a walk.

When is the best time to visit?

Sunrise and sunset are the most striking times to climb Urgull, when the light over La Concha Bay and the city produces some of San Sebastián's best views. During the day, especially in summer, the summit can get crowded, so an early morning visit tends to be quieter.
