Stora Sundby Castle in Alberga was designed like a calendar with four large towers, twelve small towers, 52 rooms and 365 windows. The park and deer enclosure are open for outdoor walks all year.

The castle itself is a private residence where interior tours are available only for pre-booked groups.
