The Botanical Garden is located on Marulić Square, not far from the Main Railroad Terminal in Zagreb.
1889 is considered to be the year of foundation of the garden, when his architectural drawing  has been made, and Professor Heinz is considered to be his founder. Since 1971, the garden is protected by the law as a monument of nature and culture, and for the last few years its greenhouses and fountains are subject to constant renovation and decoration.

In the Botanical Garden there are about ten thousand plant species from Croatia and the world, and it is also interesting that in 1911 a marine aquarium was built within the garden, which today, unfortunately, no longer exists.
