Jan Adam von Auersperg came back from Italy with six seedlings of chestnut at the end of 18th century. He ordered that the seedlings were planted on the north side of Nasavrky hill. This happened between 1776 to 1778. The plants were the start of Kaštanka. In passing time, the set was expanded a lot. Kaštanka had over 110 trees in the turn of 19th and 20th century.
