History
The remains of protohistoric ceramics found in the Barcelones estate and the vestiges of a field of silos from the Iberian era in the Torrent Gran, constitute the first indications of the existence of habitat in the municipality.[4]
Traces of a Roman villa were found in Sant Hilari.[5]
From the 15th-16th century onwards, the town grew with buildings and population, even during times of epidemics.[6]
