Castle de Bueren (also called Castle van Kwatrecht), located Kalverhagestraat in Melle (Belgium), illustrates the transition from a fortified, medieval water fortress to a residential castle. Though the double moat still refers to an era of fortification, the residence function predominates as can be deduced from the large windows.
The nucleus of the building goes back to the 16th century, but during a neo-Renaissance expansion in the 19th century, a fixed entrance bridge and a corner tower were added, while the entrance bay was renewed.
