The St Mungo Museum of Religious Life and Art is located in Cathedral Square, on the lands of Glasgow Cathedral off High Street. It was constructed in 1989 on the site of a medieval castle-complex, the former residence of the bishops of Glasgow, parts of which can be seen inside the Cathedral and at the People's Palace, Glasgow. The museum building emulates the Scottish Baronial architectural style used for the former bishop's castle. The museum opened in 1993.
The museum houses exhibits relating to all the world's major religions, including a Zen garden and a sculpture showing Islamic calligraphy. It housed Salvador Dalí’s painting Christ of Saint John of the Cross from its opening in 1993 until the reopening of Kelvingrove Art Gallery and Museum in 2006.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
