Hadovka, Cultural monument and homestead in Hanspaulka, Dejvice, Czech Republic

Hadovka (also Serpentka) is a homestead at Evropská 10/64 in Dejvice, Prague, rebuilt in the Neo-Gothic style by architect Josef Niklas after 1850. Part of the west wing was demolished during that reconstruction, giving the building an irregular plan. A Baroque Chapel of the Holy Trinity from around 1700, altered in 1853, stands on the former grounds and has an interior painted by Josef Navrátil.

In the first half of the 16th century the site held seven small vineyards, and a wine press is documented there by 1602. Imperial notary František Ferdinand de Serponte acquired the property in 1661, giving rise to the name Serpentka. In 1850 factory owner Gabriel František Janoušek bought it and had architect Josef Niklas rebuild it as a Neo-Gothic chateau, demolishing part of the west wing.

The name Hadovka arose from a mistaken Czech rendering of the surname of imperial notary František Ferdinand de Serponte, who bought the estate in 1661; serpens is Latin for snake, and the earlier form was Serpentka. The homestead later served as a summer residence for the provosts of St Vitus Cathedral, who had a private chapel installed in the building.

Hadovka stands at Evropská 10/64, on the Hanspaulka side of Evropská street; the tram stop named Hadovka on that street serves it. The baroque Chapel of the Holy Trinity, rebuilt in 1853, stands on the former estate grounds. The homestead itself is not open to visitors, so the chapel and the street front are what can be seen from outside.

The name Hadovka is a mistaken Czech rendering of the owner's surname: imperial notary František Ferdinand de Serponte bought the estate in 1661, and serpens, Latin for snake, turned Serponte into Serpentka and then Hadovka. The tram stop on Evropská and the Office Park opposite carry the same name.
