Monks in ancient times grew and collected herbs with great care for the benefit of the sick.
Data demonstrating scientific examination and landscaping of the monastery's natural environs reach back centuries.

In 1830 as many as 80 tree and bush species were to be found on the Archabbey's lands. It was through the design of Fábián Szeder in the 1840's that the current form of the arboretum took shape.

Today the arboretum has several hundreds of tree and bush species, many of which are rare species and varieties in Hungary.

The arboretum of the Archabbey is a place for recreation and relaxation, but it is also home to educational work and scientific research. In addition to these values, the area also has a rich songbird population.
