Museumszentrum Burg Linn, Medieval castle museum in Krefeld, Germany.

Museumszentrum Burg Linn is a museum complex in Krefeld's Linn district, made up of Burg Linn, a polygonal ring castle first documented in the 12th century, the baroque hunting lodge in its outer bailey, and the Archaeological Museum. The castle was destroyed in 1704 during the War of the Spanish Succession and restored from 1926; its bergfried, re-roofed in the 1980s, now serves as a viewing tower over Linn and the castle park.

The castle dates to the 12th century, when the lords of Linn held it; the knight Otto von Linn, the first known castle lord, died around 1220. In 1704, during the War of the Spanish Succession, the castle was completely destroyed. Renovation only began in 1926, when it was rebuilt as a state museum; in the 1980s it received a historically unsuitable roof and the bergfried was raised as a viewing tower.

The collections display objects from Roman and early medieval graves in the region, including glass vessels and the burial of a Frankish prince. Visitors can see how people lived and were buried here centuries ago.

Visitors should know that the site consists of different areas that can be explored on foot, with most parts being easily accessible. It is helpful to allow enough time for a complete visit, as both the buildings and the indoor collections deserve attention.

Excavations here uncovered artifacts from the Battle of Gelduba in 69 AD, including weapons and personal items from that conflict. The museum also displays a detailed model of the Roman fortress Gelduba, reconstructing its layout from 200 AD.
