Today's arboretum and botanical garden in Vysoké Chvojno dates back to the end of the 19th century, when the then owner and administrator of the local estate, Margrave Alexandr Pallavicini, purchased the so-called Dašice farming estate and the adjacent land with the intention of building a chateau and a chateau park. The castle was intended for his son Karel who died tragically while hunting soon after the work began. In the end, all that was left of the project was the construction of the castle park and the planting of the arboretum. The park and arboretum were designed for Pallavicini by forester Adofl Laufke Sandtner in the English style and tree species from all continents of the northern hemisphere were brought to the park. Today, there are more than 60 species of conifers and more than 150 species of deciduous trees, including some rare trees such as Jeffrey pine, California incense cedar and Liriodendron. At the edge of the arboretum there is a zoo with wildlife, which was added to the park in 2009.
