On the steep Biscay coast near Bermeo, Gaztelugatxe appears as a rocky islet thrust into the Atlantic, linked to the mainland by a narrow stone causeway. At its summit stands the hermitage of San Juan de Gaztelugatxe, a small sanctuary whose origins lie in the early medieval period and whose present building dates largely from the nineteenth century.the reform of 1886
Gaztelugatxe: a hermitage on a Basque sea rock
Gaztelugatxe is an islet on the Bay of Biscay coast belonging to the municipality of Bermeo in the Basque Country, lying between Bermeo and Bakio and forming part of a protected natural area.an islet on the coast of the Bay of Biscay The name is Basque and has been interpreted as referring to a “castle rock” or an “inaccessible castle”, and the shape of the sea?washed cone of stone makes those meanings tangible.castle rock or inaccessible castle

The stone bridge and the long climb
The most striking man?made feature of Gaztelugatxe is the stone bridge and staircase that link the mainland cliff to the hermitage at the top of the rock. From the coastal road between Bermeo and Bakio, a path drops towards the sea, meeting the bridge where it springs out from the shore and spans the waves in a series of arches before turning into a cobbled track that winds upwards.travelling along the road between Bermeo and Bakio The climb continues along a staircase of well over two hundred stone steps, marked by small crosses that echo the Stations of the Cross and underline the devotional character of the ascent.more than two hundred and forty steps
At the top, the staircase reaches a small forecourt in front of the hermitage door, where a bell hangs in the belfry. Local custom links the bell with making wishes and marking a visit, and the vantage point offers wide views along the pale limestone cliffs towards Cape Matxitxako and back towards Bakio.San Juan de Gaztelugatxe and Aketze The hermitage belongs to the parish of San Pelayo in Bakio, tying this sea?bound sanctuary administratively to the inland village that serves as one of the main approach points.the parish of San Pelayo in Bakio
Landscape, legends and protected status
Gaztelugatxe sits within the San Juan de Gaztelugatxe Protected Biotope, a coastal strip of around 158 ha between Bakio and Cape Matxitxako where cliffs, coves and offshore rocks form a distinctive stretch of the Bizkaia shoreline.the Gaztelugatxe Protected Biotope The islet itself is mainly pale limestone, rising sharply from the sea and creating a natural platform for the hermitage that catches Atlantic swell on three sides. Nearby stands the separate rock of Aketze, another steep islet that emphasises how strongly the sea and geology shape this part of the Basque coast.
The hermitage and its setting are bound up with local stories, including a legend in which John the Baptist is said to have arrived by boat at Bermeo and walked towards the rock, leaving three footprints on the way before reaching the site.Saint John the Baptist got to there after disembarking in Bermeo Over the centuries the hermitage has suffered damage from storms and raids, including attacks by privateers such as Francis Drake in the sixteenth century, and has been rebuilt to restore its role as a small church above the sea.fires and plunderings by privateers such as Francis Drake
