Frederikssund Museum is Roskilde fjord's cultural history museum. Frederikssund Museum's new permanent exhibition deals with the interaction between man, life around the fjords and Frederikssund's history.
Frederikssund Museum is located just above the Crown Prince Frederiks Bro at Hornsherred in the historic red building from 1893. In the late 1900s, the old Færgegård (ferry house) was used as a guesthouse, where there were both guest rooms, kitchen and utility room that was often rented to families with children who would like to experience the fjord and the scenic surroundings around the area. It is said that Mr. Lorentzen who was hiring out of the farm at that time was a nice man towards the children and were allowed to pick wild raspberries in the woods behind the farm.
