Ordensburg Vogelsang is a former National Socialist estate placed at the former military training area in Eifel National Park. The landmarked and completely preserved estate was used by the National Socialists between 1936 and 1939 as an educational centre for future leaders. Since 1 January 2006 the area has been open to visitors. It is one of the largest architectural relics of National Socialism. The gross area of the landmarked buildings is 50,000 m2.
The three buildings at Eifel have been known as 'NS-Ordensburg' since 1935. The first phase of the project was the construction of the Castle of Vogelsang, which with up to 1,500 workers took only two years. Several much bigger buildings were also planned, such as a huge library to be called the 'House of Knowledge' measuring 100 metres by 300 metres, a 'Kraft durch Freude' hotel with 2000 beds, and the biggest sports facilities in Europe. Construction at the site halted on the outbreak of war.
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.
