Arboretum Mlyňany is located nearby Zlaté Moravce, in the cadastre of villages Tesárske Mlyňany and Vieska nad Žitavou. Arboretum was established by a Hungarian nobleman, Dr. Štefan Ambrózy-Migazzi, in the year 1892 and it represents the greatest collection of wooden plants in Slovakia.

Dr. Štefan Ambrózy-Migazzi, the founder of Arboretum Mlyňany, was born in Nizze in 1869. After graduating from high school in Terezian in Vienna, he studied law at universities in Vienna and Budapest. He was fascinated by evergreen trees since his childhood. His passion was also encouraged by frequent journeys in southern Europe. These journeys inspired him to create the Arboretum.


Thanks to his marriage with Antónia Migazziová in 1892, he gained a mill manor. Later he bought the oak-hornbeam grove in Vieska nad Žitavou as a part of his manor.

Jozef Mišák, a specialist coming from Hořice in Czech Republic, participated in the building of the park from the very beginning. The area of oak-hornbeam grove was 40 hectares large and there were gradually added new trees imported from Germany, France and England. The main goal was to plant the highest number of foreign wooden trees and prove that they can sustain in our Slovak conditions.


Under the leadership of builder Guttmann, the manor-house was finished in 1894. The building of the characteristic tower was finished in 1905. The first plantings were realized near the manor-house in 1894. The junipers (borievka virgínska) were planted on the corners of the manor-house and (cezmína ostrolistá) near its backside.

Except for these species, there was also planted laurel (vavrínovec lekársky - Laurocerasusofficinalis), heather (vresovec mäsový - Ericacarnea), pachysandra vrcholová (Pachysandraterminalis) and experimentally indigo tree (indigovník - Indigoferagerardiana).

After finishing the building of the manor-house the great landscaping was done in its surroundings to create a garden uniform in style. As a result, there were terraces created supported by long stone walls. The part of the platform in front of the manor-house is parterre. The system of terraces provides appropriate conditions as a stand for species requiring light and drought. They ripen very well in the autumn and do not suffer so much from frost. In 1901, there was a significantly broadened range of evergreen species. It achieved its peak in 1905 – 1910 when the basic assortment of species was obtained.


Ambrózy left the Arboretum in 1914. He asked J.Mišákov to take care of it and he settled down in his property in Tana in Hungary. He founded an arboretum in Jela in Hungary, where he continued the job and developed his gardening skills. However, the insidious disease together with other circumstances made it impossible to finish his piece of work. He died in 1933. J. Mišák continued with the landscaping of the building even without the owner's funds. In 1925, about 300 taxa of sempervirens (evergreen trees) were collected in the Arboretum. As a tireless advocate and propagandist of the Sempervirents, he stood up for their defense in the controversy that arose after the catastrophic winter of 1928/1929. Despite his advanced age and deteriorating health, he was constantly trying to introduce another successor. He died in December 1939.  As a co-founder of the Arboretum, he credited the building a world-famous name. 

After 1931, the gardener Jozef Richtár, a conscientious and devoted pupil of J. Mišák gradually took care of the building.

He urged for the building to pass into the hands of the state. After the war, the building was nationalized and passed to the Board of Education and Enlightenment.

The arboretum was declared a nature reserve and became an independent scientific institute of the Faculty of Science of Comenius University. Experienced gardener Daniel Kovalovský began rescuing, reconstructing and expanding the building. It was not an easy task, because the main trees were aged and weakened. He undertook this mission successfully. He also actively contributed to the introduction of many foreign woody plants. Later, the Arboretum was taken over by the Slovak Academy of Sciences, which still manages it.
