More from the excursion we organised last saturday, with the militairy herritage foundation ( stichting Militair Erfgoed Groot Amsterdam)
www.stelling-amsterdam.org for more info.
Fort Uitermeer, the militairy tried to blow it with explosives .. didnt work !
Cleaned and restored by the stichting Herstelling ... a gouvernement youth program, to teach "kans arme jongens" how to work again, most of them are ex drugs users.
the manager of Herstelling explaning how the lock was digged out, was under the ground for years but now visable again.
the meaning of the lock or sluice was to let the water from the river "de Vecht" in to the lower land in front, flood the land to keep the enemy at a distance ... thats how the defence line works !
