Průhonice Castle Park is one of the most significant castle parks in the Czech Republic. Since 2010, it has been protected as a national cultural monument. Later in 2010, it also has been included in the UNESCO list of World Heritage Sites (as part of Historic Centre of Prague). It is described as original masterpiece of garden landscape architecture of worldwide importance. It has area of 250 hectares (620 acres). It was founded in 1885 by Count Arnošt Emanuel Silva Tarouca.
The Dendrological Garden was founded in the 1970s. It has an area of 73 ha (180 acres). There are about 5,000 taxa of woody plants and perennials, which makes it one of the largest collections of ornamental plants in the country.
The Romanesque Church of the Nativity of the Virgin Mary is located in the park. It is the oldest preserved building in the municipality.
The Neo-Renaissance castle is only partially open to the public, but it is still possible to admire its beauty, for example, in the Knight's Hall, which is a popular place for wedding ceremonies or in its courtyard.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
