The Canal of Corbulo, or Fossa Corbulonis, was an ancient canal that connected the rivers Rhine and Meuse. It was constructed by general Corbulo, who was governor of Germania Inferior in 47, although construction may have lasted longer. The advantage of the canal was that rivers ships from the Rhine could reach the estuary of the Meuse without sailing offshore on the dangerous North Sea. At the estuary, called Helinium, seaworthy ships were ready to transport cargos to Britain. The canal is still in use.
