Location: in the Plaza de San Juan, within the walls of Laguardia. 44 km away from Vitoria, 18 km from Logroño, 26 km from Haro and 7 km from Elciego.
Built in several phases between the twelfth and sixteenth centuries, with some later additions, the church of San Juan is essentially a Gothic church, originally conceived as a church-fortress, with one of its walls built-in the medieval city walls and provided with a defensive tower that protected one of the entrances to the town.
It has a valuable portal from a period of transition from Romanesque to Gothic, with archivolts, columns and sculpted capitals. It also had a Gothic one, that was destroyed in the sixteenth century in the course of reforms. That same century, after the end of the medieval wars between Navarre and Castile, the military tower became the current steeple.
Other architectural and sculptural elements of interest include several Gothic rose windows; the reliefs of the central choir, with such singular figures as a monkey playing a drum, and the side choirs and their decorated arches, in which you can see, among other figures, a grape picker with a basket full of grapes.
The Baroque altarpiece stands out too, and so does the Chapel of Pilar, which houses a polychrome sculpture of the Virgin from the thirteenth or fourteenth century.
The church was declared a national monument in 1984.
