Löwenberg Castle, Medieval castle in Murten, Switzerland.

Löwenberg Castle is a former wine estate and country manor near Murten, not a hilltop fortress. Its core is a late-Gothic cube built in the 15th or 16th century as a winegrower's house; a 17th-century remodelling nearly doubled the floor area and added a corner turret oriel and a stepped gable. An 18th-century clock in the gable and a bell-shaped turret roof date from later work, and an orangery was added in 1888.

Löwenberg was first recorded in 1267 as "Loenber" in a charter between Rudolf IV of Habsburg and Peter II of Savoy. In the late Middle Ages it belonged to the Fribourg noble family Velga; in 1476 Bern and Fribourg exempted Jakob Velga's vineyard from taxes after the siege and battle of Murten. Sebastian von Diesbach acquired the estate in 1511 and left the oldest visible traces on the manor house. From 1794 the de Rougemont family converted it into a country estate and enlarged it to about 75 hectares. The SBB bought it in 1973 and built its training centre from 1980 to 1982.

The name Löwenberg appears in 1267 as «Loenber» in a charter between Rudolf IV of Habsburg and Peter II of Savoy. The estate belonged to the noble Velga family of Fribourg in the late Middle Ages; in 1476 Bern and Fribourg exempted Jakob Velga's vineyard from taxes after the siege and battle of Murten damaged it. In the dining room, wall panels painted around 1840 show large bunches of grapes, a reference to the estate's wine-growing past.

The estate lies just outside Murten's old town, and the grounds are reached on foot; the main house is not a public museum but part of the SBB training centre, so visits are limited to the exterior. Look for the free stair with fountain against the vineyard wall, added after the French Revolution when walls and enclosures were levelled.

The SBB training centre built 1980–1982 on the estate is called Centre Loewenberg, and some of the manor house rooms are used for its courses. The estate was sold to the SBB in 1973; restoration of the historic buildings accompanied the new construction.
