Santa Maria de Serrateix, Benedictine monastery in Serrateix, Catalonia.

Santa Maria de Serrateix is a former Benedictine abbey, now a parish church, on the BV-4235 road in the Berguedà comarca. Its church, begun in 1077 and consecrated in 1126, has a single long barrel-vaulted nave of seven bays, a transept and a central apse with Lombard bands and blind arcades. The side apses were replaced at the end of the 16th century by large late-Gothic rectangular chapels, and a fortified bell tower with battlements rises on the west facade.

Monks settled at Serrateix around 940, and from 977 the community was placed under the protection of the Counts of Cerdanya and Besalú, with Froila as abbot (977–993) and thirteen monks in residence. A new church begun in 1077 was consecrated in 1126. In 1373, with only six monks left, Abbot Berenguer de Lluçà rebuilt the bell tower, and the monastery later passed under the Bishop of Urgell.

The two large rectangular side chapels replaced the Romanesque lateral apses in the late 16th or early 17th century, in a late Gothic style; at the same time the roof was raised, the dome removed and a gallery of windows added above the central apse. The abbey's heraldic shield, in its 17th-18th-century Baroque form, appears on the lintels of doors and windows.

The monastery sits next to the BV-4235 road and is easy to reach by this route. Visitors can enter the church when services are not happening, and should dress respectfully and keep quiet in this active religious space.

The Gothic tomb inside the nave, long taken for the burial of Count Oliba Cabreta, is in fact that of Ponç de Vilaró. The recumbent knight lies with hands on his chest and sword at his waist, his head and feet on cushions, and the family shield appears three times. Oliba Cabreta died a monk at Montecassino in 990.
