Unlike the botanical garden in Troja, this one is situated near the city centre (one tram stop from Karlovo namesti). It belongs to the Faculty of natural sciences (Charles University).
The great thing is that the entrance to the outside exposition is free of charge. So you can go there regularly and observe how nature is changing according to the actual season. I cannot wait to see some first early spring blooms .-)
You can find quite a number of benches there, some of them exposed to the sun, some hidden in the shade. So if you want to chill out, relax or simply read a magazine or a book in a quiet environment, you will be satisfied there.
