This year we celebrate the 37th Open Monumentendag (Open Monuments Day) in Flanders.

More than 1100 activities have been prepared by heritage professionals and volunteers.

The theme is architectural heritage, which we adapted to the baseline "In stijl!". From celebrating 100 years of art deco, looking at the intricate building styles of military buildings to architectural walks all over Flanders. There is something to do and discover for everybody!
