In 1870 a large restoration started by the French architect Parent. He adapted the castle to the living standards of his period. The exterior was left mostly intact, apart from a couple of pseudo-renaissance style adaptions. The interior was completely remodeled so that nowadays we can see how a large, 19th century, mansion looked like.
Ooidonk Castle lies east of the village of Bachte-Maria-Leerne, a few kilometers south west of Gent. The castle's name is a derivation of the word 'hodonk' which means a higher piece of land in a swamp.
