Some information from Wikipedia:
The Chișinău Botanical Garden of the Academy of Sciences of Moldova was founded in 1950 by the Russian Academy of Science. The garden is located in Chișinău, Botanica, Moldova and covers an area of 76 hectares. In 1973, a new botanical garden was established in the Botanica sector of Chișinău. Two years later, the garden was given the status of a Research Institute of the Academy of Sciences of Moldovan SSR. There are around ten thousand species of plants in the garden.
From my side. It is a nice place to visit when you are in Chisinau and now you can find there a Geocache :).
“In order to get inside, you have to pay the entrance fee” The cache isn't so easy tu find, but be sure it is there. Please take a picture log of the container.
Good luck!
