I can’t believe people are still pushing this nonsense.

Medievals had advanced hydraulic engineering.

Some examples:

  1. 14th century lavatorium at Gloucester Cathedral.
  2. 12th century very detailed waterworks plan.
  3. Aqueduct built by crusaders at Krak des Chevaliers, Syria.

If you want to read a really good book on medieval hydraulic engineering this is a great and detailed study.
