Another surviving gate in Amersfoort is Monnikendam. The name (Monk’s Dam) was a tribute to Augustinian monks from De Mariënhof, a nearby medieval monastery. The impressive water gate with twin towers was built at the start of the 15th century. There is a footpath on top of Monnikendam. You can sense what it might have been like as a guard watching over the city during the Middle Ages. There is also a lovely upscale restaurant inside.
