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: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.
