Location: on a hill 1 kilometer far from Peciña, a small village in the municipality of San Vicente de la Sonsierra, and 4.5 km away from San Vicente.
The church of Santa Maria de la Probática Piscina de Jerusalén is usually considered the main Romanesque temple in La Rioja. It is a small chapel dating from the twelfth century, built in ashlar masonry to commemorate the entry of Prince Ramiro in Jerusalem during the First Crusade. Apparently, Don Ramiro, grandson of King García of Nájera, entered the city through the door of the Probática Piscina, the head of a detachment of soldiers from Navarre. In his testament he stated that a church with the emblem of the kings of Navarre should be built in memory of that event.
The temple has the characteristic features of Romanesque architecture, with a single nave and a beautiful semicircular apse. The portal and the windows are decorated with stone balls, plant motifs and capitals. The only further addition is a big coat of arms from the XVIth century, placed above the entrance arch. The interior is bare, with some remains of Romanesque paintings in the apse.
The chapel was declared a national monument in 1931. Apart from its artistic value, it is located in a beautiful setting with an extensive view of the vineyards of the area. A few meters from the church there’s a medieval necropolis from the tenth century, with numerous anthropomorphic tombs carved into the rock.
