Old Botanical Garden of Göttingen University

It is located in the Altstadt at Untere Karspüle 1, adjacent to the city wall, Göttingen, Lower Saxony, Germany, and open daily.

The garden was established in 1736 by Albrecht von Haller (1708–1777) as a hortus medicus, and gradually extended via adjacent plots within and without the city wall.

In 1967, as the university's natural science faculty began its relocation to a site north of the city center, two new botanical gardens were there established (the Neuer Botanischer Garten der Universität Göttingen and the Forstbotanischer Garten und Arboretum), but the old garden continues.

In one of the most recent changes, its systematic garden was converted in 2003–2007 from a century-old taxonomic structure to one reflecting contemporary molecular genetics.

Today the garden contains 17,500 accessions representing about 14,000 species, and it forms one of the largest and most significant scientific collections of plants in Germany.
