The Cathedral of Notre-Dame-de-Nazareth in Orange dates originally from the 4th century. It was rebuilt in the Romanesque style in the 12th century. Guillaume des Baux, Prince of Orange, attended its consecration in 1208.
After being sacked by the Huguenots in 1561, it was restored early in the 17th century following the original plan. Towards the end of the 18th century, Orange’s last bishop, Monseigneur du Tillet, undertook its restoration andadded to its furniture (stalls, main altar, etc). Converted into a temple to the goddess of Reason during the Revolution, it was later returned to the church. In the 19th century, it was decorated with frescos and stained-glass windows, and the eastern porch was reconstructed in the neo-gothic style.
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.
