The Putse Moer is a swampy area northeast of Putte and west of Kalmthout, partly on Dutch and partly on Belgian territory. A small part belongs to the Kalmthoutse Heide.
The Antitankgracht was constructed just before the Second World War to stop German tanks. Fortunately, that is no longer necessary today, but it does provide us with a nice location to cycle through.
The fort was built between 1909 and 1914 to prevent an invasion. After 1918, the fort was rebuilt, its weapons replaced, and its ventilation and emergency exits were adapted.
