Finally it was sold 1900 for a symbolic price of 1000 Goldmark to the German Castle Association, which had been founded a year earlier as a private initiative to preserve castles in Germany. The Marksburg is the head office of this organisation since 1931. In March 1945, the castle was damaged heavily by American artillery fired from the other side of the Rhine. In the 1990s the castle was copied in the German culture village Ueno on the Japanese island Miyako-jima."@en .
