The Basilica of Notre-Dame de Nice was built between 1864 and 1868. It was designed by Louis Lenormand and is the largest church in Nice, but is not the cathedral.
Inspired by Angers Cathedral, it is built in the Neo-Gothic style. Its construction was motivated by a desire to frenchify the city after the County of Nice was annexed to France from Italy, and at the time Gothic buildings were supposed to be characteristically French. Its most prominent features are the two square towers 65 m high, which dominate the east front together with a large rose window featuring scenes of the Assumption of Mary.
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.
