Monastery of Santa Maria de l'Estany

That same year, Bishop Berenguer Sunifred de Lluçà promoted the introduction of a community of Augustinian canons, whose members came from the cathedral canonry of Vic, who followed the bishop in his attempts to reform it, something that he was unable to achieve within his community due to strong opposition. The canonry of L'Estany was closely linked to that of Vic Cathedral, and its first known prior was Bernat Compar (or Bompar). Over time, it became increasingly important, both for its influence over other monastic centres in Catalonia and for the goods it received, which spread across a wide territory, especially in Bages and Osona.

In 1364, the canonry sold many of its possessions to acquire the Oló estate, which ultimately provoked the opposition of its inhabitants, who managed to raise the necessary capital to buy it back, which aggravated the situation of confrontation that had arisen, to the point that in August 1395 the monastery was attacked and set on fire. The destruction was such, that the community was forced to disperse. This made it easier for the canonry to divide into different factions, in favour of remaining in Manresa or other centres, while the bishop of Vic fought for the return to L'Estany, which he did not achieve until 1436.

The architectural ensemble of Santa Maria de l'Estany is made up of the church, the cloister and various outbuildings around the latter, where there is now a museum. Restoration of the complex began at the end of the 19th century, but the most decisive work was carried out from 1931 onwards,mainly affecting the church and the cloister. The church has a single nave and transept. It has a chevet formed by a large central apse (that of the nave) and two smaller apses, open at the transept.
