Obora Hvězda, Natural monument in Liboc, Czech Republic.

Obora Hvězda is an 85.6-hectare forest park in Liboc, Prague 6, centred on the Star Summer Palace, a two-storey Renaissance building with a pale weathered facade, rows of small dark windows and a steep pitched roof of reddish-brown tiles. Eight straight avenues radiate from the palace, and a stone boundary wall with four gates encloses the reserve.

The forest, first recorded as Malejov in 993, was donated by Duke Boleslaus II to the newly founded Břevnov Monastery. Ferdinand I bought it from the Benedictines and established the New Game Reserve in 1534; his son Ferdinand of Tyrol added the Litovice stream valley and laid the foundation stone of the Star Summer Palace in 1555. Troops camped here repeatedly in the 17th and 18th centuries, and the reserve was opened to the public in the 19th century.

The name Hvězda comes from the Star Summer Palace at its centre, built from 1555 for Ferdinand of Tyrol. From the Libocká, Břevnovská and Bělohorská gates, three tree-lined avenues converge before the palace. July pilgrimages to St Margaret, whose relics Přemysl Otakar II gave to St Vitus Cathedral, were held here until 1910.

The park welcomes visitors year-round along its network of walking and cycling routes suited for different fitness levels. Spring and summer offer the best conditions for exploration, as trails are well-maintained and wildlife is more active.

The eight-rayed star of paths was laid out in the Renaissance, lined with apple and pear avenues; the name Hvězda is documented only from 1592. The wooden fence was replaced by a stone wall in 1541, and the Bělohorská Gate was added in 1574.
