Vliet (canal)
The canal was dug in 47 AD under command of Roman general Corbulo, who wished to connect river Rhine, of which the current Oude Rijn stream in Roman times was the main branch, to the Meuse estuary. It is unclear what the canal's trajectory was beyond the current city of Delft; the Delfshavense Schie canal, which connects Delft to the Nieuwe Maas river was not dug until 1389.
In the Middle Ages the Vliet was an important trade link that attracted all kinds of trade, as it flowed through the heart of the County of Holland.[1] Windmills have been constructed alongside the Vliet, including the completely renovated mill 'De salamander' in Leidschendam. The Vliet area was particularly attractive among richer families, who built their mansions along its banks.
