On 2 December 1998 this site, together with twelve other Flemish beguinages, was added to the UNESCO World Heritage list. In this way, UNESCO both recognised the site's exceptional universal value and expressed its commitment to ensure its protection and conservation. The Flemish beguines are a unique testimony to the medieval mystical movement which produced tehm. Beguines were 'religious women', widows or spinsters who who wished to live an independent but committed life outside the recognised orders with their vows of fidelity and poverty. They organised themselves in self-supported 'cities of peace', with architectural and urban qualities. This beguinage, located in the former Warande (castle domain), is characterized by the early 18th century gatehouse and elongated tree-lined square. Its Calvary, chapels and Lourdes grotto reveal a lively and popular faith, while the museum illustrates the beguinage culture.
