Fortress Muiden : Keet Gate, about 1905.
Like the other gates in Muiden this was nothing more than a coupure in the fortress wall. To the right the shoulder angle of Bastion IX and to the left the shipping lock at the Keet Gate. The Keet Gate itself is situated behind the small building just above the boats in the moat. Behind the trees the roof of the artillery shed.
