Lubliniec Castle, Medieval castle in Lubliniec, Poland

Lubliniec Castle stands at Grunwaldzka 40, rebuilt in the 17th and 18th centuries and given its present Neoclassical facade in the 18th century. After 2005 only the outer walls, historic vaults on the ground floor and a few old staircase steps survived; a five-year restoration led to the opening of Hotel Zamek Lubliniec in 2010.

Lubliniec Castle was first mentioned in 1397, when it belonged to Duke Władysław Opolczyk; the Opole-Racibórz dukes held the Lubliniec lands for several centuries. After the death of Duke Jan Dobry the duchy passed to the Habsburgs, and the castle was leased out, changing tenants until Jan Kochcicki, its tenant from 1576, bought it in 1587 and rebuilt it as a family seat. A fire in 1650 destroyed part of the building, which was rebuilt as a Baroque residence; in 1655 the Jasna Góra image was sheltered here. The last rebuilding in the 18th century gave the façade its present Neoclassical appearance.

The castle's name recalls the German past of the town, which was called Lublinitz; from the early 18th century the Schloss Lublinitz commune used a seal showing a two-storey castle with two towers and a gate. Today the building serves as Hotel Zamek Lubliniec, opened in 2010 after a five-year restoration, and a boutique spa occupies the old cellars.

The castle stands at Grunwaldzka 40, now operating as Hotel Zamek Lubliniec after its 2005–2010 restoration. Visitors enter through the hotel, so access to the historic cellars and ground-floor vaults depends on the hotel's opening. The building was struck from hospital use in 1979 for poor technical condition before restoration began.

The castle's 18th-century classicist facade hides a much older core: the 1650 fire destroyed part of the building, which was rebuilt as a Baroque residence. From 1848 to 1892 it housed the Royal District Court for the Lubliniec district, and from 1854 to 1874 the district administration.
