Schiffgraben in the Eilenriede

The Schiffgraben is an artificial canal in Hanover. As early as the Middle Ages, peat and wood were transported from the Altwarmbüchener Moor via the Eilenriede and the Aegidientor to the town via the nine-kilometre-long watercourse. The canal was particularly important for Hanover's trade and economy. Only a 700 meter long section of the original ship moat has survived today. The rest is piped underground in the city.
The increasingly silted up water in the Eilenriede is called Bauengraben or Neuer Schiffgraben.

In the meantime, unfortunately, it's more of a dry hollow than a canal. On both sides there are narrow paths that are nicer to walk on than on the broad main paths.

The Schiffgraben was a canal built in the Middle Ages between the Aegidientor in the city and the Altwarmbüchener Moor. It was used to transport peat and wood into the city and, from tax thief, was part of the Hanoverian Landwehr, a border security system before the actual city fortifications.
