The "Academic Forestry Garden" on Schiffenberg was founded in 1825 as an institute for forestry studies that was independent of the university. It is considered the teaching and experimental garden of the oldest university forest institute in the world. Although the forest garden is a very special gem in the region, this special garden has almost been forgotten.

There is also a small pond in Forstgraten and next to it an open house with a wooden organ.
Here you can hit 10 different wooden trunks with a club made of cherry wood and listen to the resulting tones. You can take a break under the canopy on wooden benches at wooden tables. This place and the whole forest garden is highly recommended as a destination.
In 1777, an economics faculty was created at the University of Giessen with new subjects such as veterinary medicine and agricultural science. This also included forestry, which first appeared in the course catalog in the summer semester of 1778. One of the first students was Georg Ludwig Hartig, who later formulated the concept of sustainability. The economics faculty failed after only eight years, but forestry was retained with its own institute in the philosophy faculty. This academic upgrade of forestry was unique up to that point; the institute was the first forestry teaching institute in the world at a university.
