The church of the former monastery of San Pedro de Graudescales (or Escaleras) is located in the Ora water valley near the cliffs of Busa. Its origins go back to the 10th century when the clergyman Mangulf built a church which was consecrated by the Bishop of Urgell in 913 . In 960 the bishop initiated the establishment of a Benedictine monastery. It passed into the parish in 1270 and, after centuries of decline and destruction, the current building underwent major renovations between 1956 and 1958 by decision of the Provincial Councils of Barcelona and Lleida.
The complex consists of a nave and three apses, the largest in the middle, and the other two giving access to the transept. The octagonal dome rises on the transept. The ornamentation is reduced to a frieze of blind arches running through the apses.
