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:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
