The Belvedere Castle, Orangery, and Park forms part of the Classical
Weimar World Heritage site designated by UNESCO in 1998. The castle was
the summer residence Duke Ernst August. He made a baroque garden which
began to evolve into a landscape park after 1758. Under Grand Duke Carl
Friedrich, after 1811, a Russian Garden was made for his wife Maria
Pawlowna. A botanical collection (the 'Hortus Belvedereanus') was made
after 1820 with advice from Johan Wolfgang Goethe. In 1994 a circular
Rose Garden was added, inspired by Humphry Repton's rosary design for
Ashridge in England.
