Fort Abcoude
Fort Abcoude is the oldest land fort of the Defence Line of Amsterdam and the only fort of the line made of bricks. The site consists of a main building with a gunpowder magazine, a cistern and sleeping quarters. The outer walls are 1.8 metres thick! From the vantage point on the eastern orillon, you can see Fort Nigtevecht.
Fort Abcoude was built between 1884 and 1887. It fell out of use soon after World War I. Because of the invention of the high-explosive shell, the fort was no longer bomb-proof.

The Plofsluis consists of five concrete bins with a relatively weak floor that span the Amsterdam-Rhine Canal. The bins could store around 40,000 tonnes of sand, gravel or debris. In wartime, the floor could be blow up, so that its contents would drop into the Amsterdam-Rhine Canal. This would block the canal and prevent the inundation water from flowing out. The lock was designed in such a way that its sides would remain upright after the explosion, so that the floor could be reconstructed and the sluice could be used again. It was never actually used.
