This church, dedicated to Saint Martin of Tours, was a real surprise to me. The single nave structure was probably erected within the 12th century. It was built in a "walking distance" off the pilgrim routes (like "San Pedro de Echano"), as the hamlet Artaiz is just about 10kms north of the "Camino Aragonés". San Martin will have been for sure a stopover for pilgrims, who had visited the tomb of Saint Martin of Tours, following the "Via Turonensis".
