Around 6-km long and constituted by 180 arches, the Aqueduct of Pegões was one of the main public works built in the 17th century in Portugal. This monumental work was designed by the distinguished architect Filipe Terzi, in order to supply water to the Convent of Christ - linking the Convent with the village of Pegões on the outskirts of Tomar, where there were four natural springs.

This aqueduct – one of the largest and most impressive in Portugal - is constituted by simple arches, with a dual layer of arches in the deepest zones, attaining a maximum height of 30 metres.
