Powsinski wild fields

In the 1970s, when the Botanical Garden was established, much of its land was farmland. Over fifty years the area has changed beyond recognition, so when looking through old photographs we often have trouble figuring out which part of the Garden is depicted in them. Nowadays we can no longer see such panoramas, as large, beautiful trees of various types, species and varieties have grown up in the area, and the once wild spaces have turned into a Garden of Eden.

Which buildings are these and where was this photo taken from?
