guy Posted March 20 Report Share Posted March 20 (edited) I saw this interesting picture (above) on Substack (Architecture & Tradition). The Aqueduct of Valens, the longest aqueduct built in Roman times, is still partially intact in Istanbul (formerly Constantinople, Turkey). It was originally completed by Valens in AD 373. The 4th-century first phase was 268 km (167 miles). Edited March 21 by guy Quote Link to comment Share on other sites More sharing options...
