Sundbyholm was originally owned by the Order of St. John, who had an abbey in Eskilstuna. After the Reformation it was confiscated to the Crown. The Sundbyholm Castle was built by the Admiral of the Navy Carl Gyllenhielm, son of King Charles IX of Sweden. The estate was given to him in 1627. The castle was later enlarged by Seved Bååts.
Sundbyholm Castle is known for the beauty of its grounds and nearby environs. It has been the subject of several paintings and drawings, the most famous of which is "The Old Castle" by Prince Eugen, Duke of Närke.
Today Sundbyholm is a hotel and offers facilities for conferences, parties and weddings.

It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
