Chapel of San Caralampio
You should not leave without knowing that you have on your right the only chapel in the world covered with scallop shells.
Originally, when it was built in 1909, it was not. Its story is the result of chance. The facade where the altar is located is south oriented and the rains continually hit its walls, which caused humidity and deterioration in the structure of the construction. Raimundo Riestra Calderón, second Marquis of Riestra, called in a builder from the town of O Grove, Anselmo Millán, in the late 1940s, to find a solution to this problem that had been dragging on for almost four decades. The man told him that a traditional way of preventing water penetration was to overlap scallop shells across the entire facade, causing the rain to run off the surface. The marquis found it a great idea and accepted the proposal. When they finished covering that facade, he liked the result so much that, as manager of the spa, he had the entire chapel covered with shells. It was a slow work that took several years. It began in the late 1940s and ended in the early 1950s.
And one last detail, if you could travel back in time 120 years to the same place where you are, you would not step on land, but you would be in the water together with the chapel. Almost all of this garden was an old salt mine that loses its origins in the most remote past. It was filled in at the beginning of the 20th century.
The chapel is the work of the architect from Ourense, Daniel Vázquez-Gulías, and was inaugurated on 28th June 1909.
