parish was established in the reign of Abad D. García 1,
in the year 1137, and housed the monastery of Osera from 1164. It
is created in the Romantic style.
There is a cemetery in the atrium, which still exists to this day
and was used as a burial place until 1855 when the municipal cemetery
was established in the centre of Ribadavia.
In the parochial building, whose primitive factory has not been
conserved, there is an apse and main chantry where, according to
the historian Sr. Murguía, ‘you can find buried people
under the floor, covered by tubular tombstones’.
