Fort du Hâ Prison was originally built in 1846 within remains of the 15th century Chateau du Hâ. The prison was taken over by German forces soon after the June 1940 occupation of France and used to incarcerate political prisoners.
On 23 October 1941, 20 political prisoners were taken from Fort du Hâ to Camp de Souge and shot in retaliation for the killing of a German military advisor in Bordeaux. The prison continued to operate after the war and was finally closed in 1967 and demolished in 1969 to make way for the French National School for the Judiciary. All that remains of the old prison now are the two towers and parts of the wall from the 15th century chateau. A memorial plaque on the site is dedicated the memory of the deported internees and resistants of Gironde who died in the Nazi concentration camps 1940–1945.
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.
