Gaztelugatxe, a stone staircase to a sea?bound hermitage
Published on 08/29/2026 at 15:35 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
On the rugged Biscay coastline near Bermeo in Spain’s Basque Country, Gaztelugatxe presents a striking combination of rock, sea and faith: a small islet linked to the mainland by a long stone stairway leading to a solitary hermitage at the summit. The sanctuary dedicated to Saint John the Baptist crowns the highest point of this sea?washed outcrop, and the entire approach, from the clifftop down to the bridge and up the steps, forms a continuous built path across Atlantic swells and pale limestone.

The name Gaztelugatxe comes from Basque and has been interpreted as “castle rock” or “inaccessible castle”, a reflection of the way the conical mass of stone rises steeply from the sea with its summit enclosed by walls and the small hermitage.castle rock or inaccessible castle The islet’s pale limestone contrasts with dark patches of vegetation and the deep water around it, while the mainland side is framed by cliffs cut by the road connecting Bermeo and Bakio.between the coastal towns of Bakio and Bermeo
