It is considered one of the prime examples of Gothic rural Gipuzkoa, besides being the first manifestation of that style throughout the province. In fact the head of the temple are visible remnants of primitive apse of the church, equipped with two separate geminated windows of early Gothic. The archaeological work on the building has confirmed that these remains are the work of the thirteenth century. The church of St. Martin in its current state, is the work of the late fifteenth century and first half of the sixteenth century and responds to the characteristics of late Gothic.

The archaeological works cited have further discovered a necropolis with tombs of slabs, outside and inside the temple and now dated between the eleventh and fourteenth centuries. However, the main discovery are the remains of a funerary chapel carved in sandstone terrain, with anthropomorphic tombs, also cut into the rock and dated to the sixth century of our era.. These remains are the oldest remains of a temple and Christian burials documented to date in Gipuzkoa.
