Sant Pere de les Puelles, Benedictine monastery in Sant Pere district, Barcelona, Spain

Sant Pere de les Puelles is a former Benedictine monastery of which only the parish church remains, on Plaça de Sant Pere. Its basilical plan retains a Greek-cross core with 10th-century Corinthian columns and 12th-century barrel vaults and dome. The 15th-century portal has a Gothic Saint Peter in the tympanum, and the 18th-century octagonal bell tower holds six bells.

Founded in the first half of the 10th century by Count Sunyer I and Riquilda de Tolosa, the Benedictine monastery was consecrated on 16 June 945 by Bishop Guilarà. In 985 Almanzor's raid destroyed it and killed or enslaved the nuns; Count Borrell II restored it. In 1147 a larger church was consecrated, and the community later moved to Sarrià in 1879.

The monastery served as a center for Benedictine religious life for centuries, shaping the spiritual character of the neighborhood. Women dedicated to monastic traditions lived and worked within these walls, leaving their mark on local devotion.

The monastery is located in the Sant Pere, Santa Caterina i la Ribera neighborhood, within walking distance of other notable sites like Palau de la Música Catalana and Santa Caterina Market. This central position makes it easy to combine with other attractions in the area.

The two-storey cloister no longer stands: it was dismantled in 1873 when the street of Méndez Núñez was opened. Its Romanesque arcades, with carved capitals, are kept at the Museu Nacional d'Art de Catalunya, other fragments are in a private estate in Sant Antoni de Vilamajor and the Museu Santacana in Martorell, and ten Gothic arches are built into a building at carrer de Sant Ignasi, 1-3, in Terrassa.
