Botanischer Garten Solingen
The garden dates to 1952 when the city opened its first greenhouse on a 4-hectare site, with the garden itself opening in 1963. In 1965 the tropical house was built (143 m², 8 meters in height), and in 1994-1995 the greenhouses were extended to 826 m² by adding a cactus house and bromeliad house.
