The Church of Saint Mary of Eunate is a 12th-century Catholic church of Romanesque construction located about 2 km south-east of Muruzábal, Navarre, Spain, on the Way of Saint James. Its origins are disputed due to lack of documentation. Its octagonal plan and the fact that it is not located in a present-day village or town but in the countryside contribute to its enigmatic nature. It is a site on the French Way path of the Camino de Santiago.
The church is built of dressed stone and its plan is a slightly irregular octagon with a little three-side apse. It presents the typical architectural features of the European Romanesque art as well as some other local Romanesque characteristics like the chessboard-shape decoration in Navarre and Aragon.Its eight walls sustain an eight-rib vault, inspired in Cordova's caliphate art.
