Ciudadela de Pamplona

Standing in a privileged spot, deep in the countryside at less than 10 km from San Sebastian, the San Marko Fort is most certainly the best vantage point in Oarsoaldea. Its perfect location makes it an important and privileged viewpoint of Gipuzkoa's coast, where you can admire the famous bays of La Concha, Pasaia and Txingudi among other places of interest. This military structure located on the top of mount Bizarain at 260 m altitude was built in the 19th century over the town of Errenteria for the defense of the area. Nowadays it does not have any military use; the San Marko Fort was occupied by the army until 1970 and today is integrated into Lau Haizeta Park, forming part of the leisure-cultural area.
