I will post more photos of this place within the next few days.
The Botanical Garden of Moscow State University. It was installed by the order of Peter the First in 18th century with the purpose to grow medicinal herbs.
In the beginning of 19th century the apothecary garden was sold to Moscow State University and became study room botanical garden.
The plan of the Garden and the photo of the reconstructed Greenhouse I uploaded from official site (in Russian).
