In the inner city of Leiden, at the crossing of the railroad to Alphen a/d/ Rijn and some waterways on the Morsweg, you can find a communication bunker.
From the street it's hard to see the bunker because of the vegetation. It is easier to see the bunker from the other side, but that's property of the Dutch Military Police (Kon. Marechaussee) so ask permission.
There is still some camouflage left, they build a brick wall around the bunker to create the imrpession that it was a regular house in the city
After the war they "cut a corner" of the bunker to make room for the cars to pass between the office building and bunker.
1x 616 communication bunker.
