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 city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
