The 7 hectare park at Royaumont reflects the transformations carried out over time, at very different periods.
The Royaumont site has retained some of its medieval features. At Royaumont the monks captured a spring 3 km away to provide water for drinking and ablutions. They also channeled two rivers (the Thève and the Ysieux) far upstream. These subdivided into an arm flowing around the abbey and another flowing through the grounds and the latrines, which it cleaned before continuing underground. These canals are still visible today.
