The park is called, in English, Park of Topiary. In case you didn't know it (and I didn't), topiary is the art of hedge and bush trimming with the end result being shapes, such as animals and whatever else takes the fancy of the guy with the trimmers.
This park is said to be the largest in the world of its kind that is opened to the public. So, I guess there are larger parks but we aren't allow to see them, so this one will have to do. The park, which sits on the River Ourthe, just across the bridge from the castle, is the brain child and also the life's work of Albert Navez.
Here you'll enjoy a walk through the park and (hopefully) admire all the work and designs of Mr. Navez. You will find hedges and bushes cut and pruned that now represent buxomy naked women lying in bath tubs and on lounge chairs, some peacocks, a life-sized Mannekin Pis (like the one in Brussels) and my favorites, a couple of crocodiles. There are of course many more.
There is a shop there for your souvenir needs and also a small cafe. read more
