Örenäs Castle, Stately mansion in Landskrona Municipality, Sweden

Örenäs Castle is a stately mansion in Landskrona Municipality, Scania, built 1914–1918 for engineer Carl Tranchell to a Baroque-style design by architect Fredrik Sundbärg. Its cream-coloured facade with a dark grey mansard roof has two main floors above a basement, two lower wings flanking a projecting centre, and a pale green multi-tiered cupola with a gold finial. A pale yellow and blue striped awning covers a ground-level terrace behind a low trimmed hedge and a broad lawn.

The present building was erected in 1914–1918 for the Swedish engineer and industrialist Carl Tranchell (1849–1919), to designs by architect Fredrik Sundbärg (1860–1913) intended to resemble a Baroque castle. During World War II it housed Danish and Estonian refugees. In 1970 it was renovated and turned into a public facility.

The castle sits right on the coast with open views across the Øresund strait toward Denmark. The surrounding park draws visitors who come to walk along the shore and take in the sea air.

The castle is located about 8 kilometers from central Landskrona and works mainly as a hotel and conference venue. Anyone hoping to see the interior should check in advance, since access is generally reserved for overnight guests and event attendees.

The architect Fredrik Sundbärg died in 1913, before the building was completed in 1918. The mansion was built for engineer and industrialist Carl Tranchell, who died in 1919, only a year after construction finished.
