These two magnificent and simple Romanesque churches appear as if by art of magic in this humble district. The church of San Martín is the most interesting and best conserved.
It was carefully restored in the 1980s. It has a nave, presbytery and semicircular apse with a semicircular window supported by a pair of columns carved with animals (quadrupeds and two-headed birds), and topped with a dust cover with pyramidal studs. The doorway is also semicircular and has four archivolts decorated with floral and geometric motifs resting on columns and capitals carved with animals (and a man being bitten by a wolf). It is protected by a graceful arcaded gallery, with seven semicircular arches which give a sensation of harmony and symmetry, supported on twin or quadruple columns. Its capitals are decorated with plant motifs. On the interior, the apse still conserves remains of the primitive wall paintings (12th century).
