The Botanischer Garten Marburg (20 hectares), also known as the Neuer Botanischer Garten Marburg, is a botanical garden maintained by the University of Marburg, located on Karl-von-Frisch-Straße, Marburg, Hesse, Germany, and open daily. An admission fee is charged.
The garden was created between 1961-1977 to replace the Alter Botanischer Garten Marburg, dating from 1810. Its construction involved movement of some 80,000 m3 of earth, creating a pond and a brook about 1 km long, as well as a major effort to build greenhouses. The garden was inaugurated in June 1977 to celebrate the university's 450th anniversary.
