Mount Urgull stretches out into San Sebastian’s bay and is surrounded by water, except for one section that connects to the Old Town. Beginning at the Aquarium, the Paseo Nuevo encircles the entire hill, which is crowned by the Mota Castle, a formidable 12th-century fortress hosting the History House Museum, granting insight into San Sebastian’s past. Historically, the mount has served as a strategic defense point for the city and military ruins such as cannons, as well as parts of the original wall that surrounded the medieval city, are still visible on the hill. But overall, Mont Urgull boasts stunning views of every part of the city from the Gros district and the Playa de Zurriola to the La Concha bay and the port.
