Plaza de la Constitución is a 2,000 sq m square in the heart of San Sebastian Old Town. Rectangular in shape and framed by 4-storey arcaded buildings, this former bull fighting arena is now a pleasant open-air space amid the maze of narrow lanes that is the Old Town. As an interesting little detail, you can still see the former arena’s seat numbers written above each of the balconies that surround the square. Take a table at the terrace of one of the restaurants and tapas bars lined around the plaza and take the pulse of the city.
