In 1790, Jan Nepomuk, Count of Lamberg founded a park where a black walnut was planted among other trees. Leopoldina Thun, born Countess of Lamberg, had a wooden chapel built under the tree in memory of her father who drowned in the Morava river. After the park opened to the public, the place became a destination of frequent spiritual visits. The tree was in a very bad condition caused by floods in 1997, when the park was under water. Thanks to professional intervention, however, the walnut tree recovered and is still the gem of the park.
