Le Havre Cathedral (Cathédrale Notre-Dame du Havre) was previously a parish church dating from the 16th and 17th centuries, and is the oldest of the very few buildings in central Le Havre to have survived the devastation of World War II. It became a cathedral and the seat of the Bishop of Le Havre in 1974, when the diocese of Le Havre was created.
The belltower dates from around 1520 and the main façade is Baroque. The building was kept unusually low because of the difficulties posed by the unstable ground. The fine church organs were the gift of the Cardinal de Richelieu in 1637, when he was governor of the town.
There is a memorial in the cathedral for the 5,000 civilians who lost their lives during the Nazi occupation of the city in World War II.
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.
