A group of buildings consisting of the church, the cemetery and the rectory, situated on the main road from Molins de Rei to Vallvidrera. The church is documented in 1032, but the first news of this site appears in a document dating from the late 10th century. The pre-Romanesque remains here demonstrate its antiquity.

During the Romanesque period, side chapels were added inside and the nave, roofed with barrel vaulting, was extended. Various reforms to the building were subsequently carried out. Lastly, in 1632, the current bell tower and main portal were built. The place name Olorda is a pre-Roman word and possibly of Basque origin. It means ‘path of the calves’.
