The Botanical garden on Sparrow Hills was established practically in the same period with one of the Seven Sisters, the main building of MSU. The garden treasury was permanently enriched by both scientific research and expeditions. Nowadays plant species from various spots of the USSR and the globe in general can be found there. Also there is a garden plants sector where you can not only see but even buy some locally grow apples and other fruit. The entrance is possible only as part of an excursion group and is to be booked beforehand.
