Foss Dyke
The Foss Dyke , also Fossedyke , is the oldest navigable canal in England . It was built in 120 AD as a Roman Canal in what is now Lincolnshire . Its length is 18 km. It connects the rivers Trent at Torksey and Witham at Lincoln . The canal has a lock at Torksey that leads from the tidal Trent into the canal.
During the reign of King Henry I of England in 1121 and again in the 18th century, the canal was renewed and deepened. More thorough maintenance work was carried out in 1840, but with the opening of the Lincoln railroad in 1846, the economic importance of the canal declined. The last commercial cargo ships delivered grain until 1972. Today the canal is almost exclusively used by recreational shipping.
