Mauritzberg, Manor house in Norrköping Municipality, Sweden.

Mauritzberg is a château and manor house built on a cliff above Bråviken bay in Norrköping Municipality, Sweden. The complex includes a main building, a former mill, and wing sections, all listed as a protected architectural ensemble.

The estate was first called Björsätter and dates to the early 1500s, when it belonged to the riksråd Morits Birgersson Grip. In 1593 his granddaughter Ebba Grip renamed it Mauritzberg after her father, Mauritz Grip, who had built the north wing. Russian troops burned the castle in 1719; Count Claes Ekeblad rebuilt it by 1725 with decorations by Carl Hårleman.

The name Mauritzberg honours Morits (Mauritz) Birgersson Grip, the privy councillor and colonel who owned the estate; it was renamed after him in 1593. His daughter Ebba Grip is credited with rebuilding the property as a säteri in 1669. Between 1912 and 1918 the owner Birger Mörner received cultural figures such as the writer Verner von Heidenstam here.

The estate now operates as a hotel across its main building, the former mill, and the wing sections. Comfortable footwear is a good idea, as the cliff terrain and surrounding forest paths can be uneven.

The north wing was added by Morits Birgersson Grip, the riksråd and colonel after whom the estate is named. His daughter Ebba Grip is thought to have rebuilt the property as a säteri in 1669, and the name Mauritzberg was recorded in 1593.
