Begin your tour in the heart of the Old Town at Plaza de la Constitución, the city’s historic main square. Designed by architect Pedro Manuel de Ugartemendía and completed in 1817, this elegant square is framed by arcaded buildings once used as bullring balconies—still marked with numbered façades. Today, it serves as a lively gathering place and hosts many of San Sebastián’s cultural events throughout the year.

Proceed to the Church of San Vicente Mártir, the oldest surviving church in the city, dating back to the 16th century. Built in Gothic style, it features a robust and somewhat austere exterior. Inside, visitors can admire remarkable artworks by the sculptor Felipe de Arizmendi, including the expressive “Medallion of Souls” and the evocative “Ecce Homo.”

Continue along Calle 31 de Agosto, one of the most historic streets in San Sebastián. Its name commemorates the devastating fire of 1813 during the Napoleonic Wars, after which this was the only street left standing in the Old Town. Today, it is a charming pedestrian lane lined with traditional buildings, boutiques, and cafés, connecting two of the city’s most important churches.

At the end of the street stands the Basilica of Saint Mary of the Chorus, an impressive Baroque church completed in 1774. Its ornate façade is framed by twin towers, with a central sculpture of Saint Sebastian. Inside, the richly decorated altarpiece dedicated to the Virgin of the Choir reflects the city’s deep religious heritage and artistic tradition.

As you exit the Old Town, enjoy views toward Mount Urgull, a historic hill that has played a key defensive role in the city’s past. While a full ascent requires more time, the lower paths and surrounding viewpoints are freely accessible and offer scenic perspectives of both the coastline and the Old Town.

Continue to the elegant City Hall, a striking Belle Époque building that once functioned as a grand casino. In the late 19th and early 20th centuries, it attracted European aristocracy and high society until gambling was prohibited in 1920. Today, the building retains its architectural grandeur and stands as a symbol of the city’s refined past.

Just beside the City Hall, take a moment to stroll through Alderdi Eder Gardens. This beautifully maintained green space, dotted with tamarind trees and colorful flowerbeds, offers a peaceful setting and lovely views of the bay—perfect for a brief pause during the tour.

Make your way to the Cathedral of the Good Shepherd, the largest religious building in the city. Completed in the late 19th century in Neo-Gothic style, its soaring 75-meter tower dominates the skyline. The interior is equally impressive, featuring intricate stained-glass windows that create a luminous and serene atmosphere.

Conclude your tour at La Concha Beach, widely regarded as one of the most beautiful urban beaches in Europe. Its crescent-shaped bay and calm waters provide a stunning natural setting. This iconic waterfront is the perfect place to relax and reflect on your journey through San Sebastián’s rich history and culture.
