On Whit Monday, May 25, no fewer than 31 locations in South Holland will open their gates, fences, and sometimes even doors during Castle Day. Of these, no fewer than 26 are located in Hollands Buiten!

Come discover and experience the past. This year the theme is ‘Love’. Who loved whom? Which bonds proved stronger than time? And how has love – in all its forms – shaped the history of these special places? Discover it for yourself and you are most welcome on this day.
