ceramic tile sign affixed to a rough-hewn stone wall

ceramic tile sign affixed to a rough-hewn stone wall. The tile is square with a white background and a blue decorative border. In the center of the tile is a circular painted portrait of a man with a beard and mustache, rendered in shades of blue and grey. He is looking directly at the viewer, and his mouth appears to be obscured by a dark smudge. Above the portrait, the words "San Juan de Gaztelugatxe" are written in a curved line in dark blue lettering. Below the portrait, the word "LAGUNTZA" is written in large, dark blue capital letters. In the bottom right corner of the tile, there is a small, illegible signature in blue ink. The stone wall behind the tile is textured and appears to be an exterior wall, possibly of a historic building. The lighting suggests it is daytime. This tile likely marks the location of San Juan de Gaztelugatxe, a famous hermitage and iconic landmark located on an islet in the Bay of Biscay, off the coast of the Basque Country, Spain, and is a significant site for the municipality of Bakio.
