The entrance to San Baudelio de Berlanga is a single horseshoe-arched door on the north wall of the building, which leads directly into the nave of the church. Upon entering the hermitage, visitors are greeted by a large circular pillar that rises to the vaults of the apse. From the top of the pillar project eight ribbed arches, which are supported at the four corners and middle of the walls of the church. These arches are horseshoe forms with corner ribs supported by small Moorish inspired squinches.
