Monumental church complex of Sant Pere is a Bien de Interés Cultural landmark in Terrassa, Province of Barcelona, Spain.
The three churches were built near the old Roman Ègara (whose remains are still preserved), which was the seat of the Bishop of Égara around the year 450 and lasted until the Saracen invasion in the 8th century.
After a long construction process, the current churches, of Romanesque design, were completed in present form during the 11th and 12th centuries during the Visigoth era.
[1] Architects, archaeologists and historians, including Francisco de Paula Villar, Lluís Muncunill i Parellada, Josep Puig i Cadafalch, Josep de Calassanç Serra i Ràfols, and Jordi Ambròs continued research on the monuments at different times during the 20th century, in order to discover the episcopal history and that of the Roman Ègara.
The work was highlighted by Puig, who made a thorough study of all historical restorations and excavations in Santa Maria and San Miguel.
