Panenské Břežany (German: Jungfern-Breschan) is a municipality and village in Prague-East District in the Central Bohemian Region of the Czech Republic.

In the first half of the 18th century a Baroque palace was built, which came to be called the Horní zámek ('upper castle').

[4] After the secularization of the monastery during reign of Emperor Joseph II, the estate fell to the Virgin Teinitz Religious foundation.

In 1909 the property was bought by Ferdinand Bloch-Bauer, a financially strong Jewish buyer involved in the sugar industry.

In the castle complex lived both Konstantin von Neurath and from 1941 his deputy (Stellvertretender Reichsprotektor), the SS-Obergruppenführer Reinhard Heydrich, with their families.

The Horní zámek Castle was occupied by Karl Hermann Frank during World War II.
