The Commandery of Libdeau is a former Knights Templar commandery, founded before 1190. It is at Toul, in Lorraine. It became a Knights Hospitaller commandery following the dissolution of the Order of the Temple in 1312 by Pope Clement V at the Council of Vienne. During the French Revolution, it was nationalized by the state and sold as a bien national in July 1794.
The only remaining buildings of the commandery of Libdeau are the gothic chapel, at Libdeau dating from the first quarter of the 13th century, and a 17th-century townhouse situated in the city of Toul.
The gothic portal of the chapel and several ledger stones coming from Libdeau have been kept since the 1960s at the Palace of the Dukes of Lorraine, home of the Musée Lorrain in Nancy.
The other buildings of the commandery were rebuilt after the Thirty Years' War and are now used for housing and farming.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
