Erfurt - International Garden Show Gartenbauausstellung

Worth seeing is the International Garden Show, an area of 100 hectares/250 acres on the site of the Cyriaksburg, a medieval stronghold on the south side of Erfurt. There is a Gardening Museum, which also commemorates the first Garden Show in 1838.

Within the Garden Show grounds are an observatory (frequent special exhibitions) and an outlook tower, both housed in towers belonging to the old Cyriaksburg. Between the towers can be seen an old woad mill, a relic of the days when the production of dye from woad was an important element in the town's economy.
