The submarine base of Saint-Nazaire is a large fortified U-boat pen built by Germany during the Second World War. Before the war Saint-Nazaire was one of the largest harbours of the Atlantic coast of France. During the Battle of France, the German Army arrived in Saint-Nazaire, in June 1940. The harbour was immediately used for submarine operations.
In December, a mission of the Organisation Todt inspected the harbour to study the possibilities to build a submarine pen invulnerable to air bombing from England. Work soon began under the supervision of engineer Probst.
The selected space was that of the docks and buildings of the Compagnie Générale Transatlantique, which were razed. Building began in February 1941. The adjacent dry-dock in Saint-Nazaire dock was the target of Operation Chariot, a British commando raid in 1942, the U-boat pens were a secondary target of the raid. The attack successfully disabled the dry-dock by ramming an explosive-filled destroyer into it, and by demolition teams wrecking the pumps and electrical system.
The base was equipped with 62 workshops, 97 magazines, 150 offices, 92 dormitories for submarine crews, 20 pumps, 4 kitchens, 2 bakeries, two electrical plants, one restaurant and a hospital. On the roof is one completed and one uncompleted M19 Maschinengranatwerfer automatic 5 cm mortar bunker.
The zone of the base was abandoned for a long time. In 1994, the municipality of Saint-Nazaire decided to re-urbanise the base, in a project name Ville-Port. The base now features several museums, including a mockup of a transatlantic liner called the Escal'Atlantic, and the French submarine Espadon.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
