The romantic Schloß Marienburg was a birthday present of King George V of Hanover to his wife Queen Marie. It was build between 1858 and 1867 as a summer residence as a refuge from official court life. The building was designed in the neo-Gothic style, which was highly popular at the time. In 1866, while the castle was still under construction, war broke out between Prussia and Hanover. After Hanover had been annexed by Prussia, King George V left the country and went into exile in Austria where Queen Marie joined her husband one year later. Because of the war, Marienburg Castle has never been finished. The castle was left uninhabited, and it remained so for almost 80 years with only a caretaker in residence. For this reason, the original design is almost completely preserved. Today the almost completely preserved interior and the countless turrets and pinnacles still overwhelm.
