The Royal Herrenhausen Gardens comprise Grosser Garten, Berggarten, Georgengarten and Welfengarten. Within this unique ensemble of parks and gardens, each is a splendid example of the garden arts of its age.
Criss-crossing its 50 hectares, geometrically precise allées and paths lead to many charming features, such as Germany's oldest hedge theatre, built at the end of the 17th century at the command of the Elector Ernst August and his consort Sophie and still in use every summer during the festival weeks.
