Olisipo

This aqueduct may have served the city of Lisbon or a local roman villa. Some 10 km from the city center, on the road from Cene&ccdil;as to Belas or Quelez, the aqueduct starts with a roman build brick dam in the Carenque River. The dam still has a length of 15,5 m, was 7 m wide and 8 m high. The capacity of the dam was 125.000 m3. Its channel can be followed over some 1300 m but its course is then lost.
In the 16th century a 'new' elaborate aqueduct system started in the same area with clear lines into the city center. The most visible part is the 'Aguas Livres' aqueduct bridge in the central- west part of the town. Unfortunately some structures of this 'new' aqueduct partly ruined the classical roman dam, see illustrations.
