George V of Hanover gave his wife Marie a hill for her birthday in 1857 and had a castle built on it in the neo-Gothic manner, with a chapel, library, ballroom and towers. The kingdom of Hanover ended in 1866 and the family left; Marie stayed until 1867, and the castle was left with rooms unfinished and furniture in place, then stood uninhabited for almost eighty years, until the family returned in 1945. It opened to visitors in the 1950s. In 2018 the Welf family announced its sale for a symbolic one euro because upkeep had become impossible; in 2020 the castle passed to a foundation, and long-running restoration continues.

History

The castle was built between 1858 and 1867 as a birthday present from George V of Hanover to his wife, Marie of Saxe-Altenburg, and also as a summer seat for the House of Hanover, which kept almost no court in Hanover while it ruled Britain from 1714 to 1837; its architects were Conrad Wilhelm Hase and Edwin Oppler. When Prussia annexed Hanover in 1866 after the battle of Langensalza, the royal family went to Gmunden in Austria and the castle stood uninhabited for almost 80 years, which is why it is so well preserved; the family moved back in late 1945, and in 1954 Ernest Augustus IV opened the castle museum (Wikipedia, Marienburg Castle (Hanover)).
