In 1898 was established the Forestry Academy at then the Philosophy-Scientific Faculty which in 1919 became Masters Forestry Faculty at the University in Zagreb. In the frame of the institute for cultivating forest and on the area of the Faculty estate at Maksimir, in 1923 a forest garden with an arboretum was made on a surface of 2.6 hectares. The garden was made in order to serve for educating students of forestry i.e. to educate them in the sphere of cultivating forests. That is the first and the oldest object which used to serve and it still serves, even nowadays as an educational object at today's the Forest Faculty. In the period of the very first years of its existence it had been produced a lot of plants which were used for afforestating.
