The Roman dam of Belas (3rd century AD) may have served the city of Olisipo or a local Roman villa (Roman villa of Quinta da Bolacha). Some 10 km from the city center, the aqueduct starts with a Roman-built brick dam in the Carenque river. The dam is still visible today (length of 15,5m, 7 m wide and 8 m high). The capacity of the dam was 125.000 m3. Its channel can be followed over some 1,300 m but then its course is lost due to the much modern Águas Livres Aqueduct that was built over the old structures. == See also == * List of Roman dams 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Roman dam of Belas」の詳細全文を読む スポンサード リンク
