A grand 17th century summer palace built for Count Václav Vojtěch Šternberg, Troja has French gardens littered with Baroque sculptures right on the river below the Botanical gardens and next to the Zoo. It was originally situated here to be opposite Stromovka royal game preserve (now Stromovka Park), which it is linked to today by a pedestrian bridge, but be warned it is no short walk to the closest tram stop once you start. Jean-Baptiste Mathey designed the palace, which Šternberg spared no expense on. Its most striking feature is the external double staircase ornamented by statues of Titanic struggles with Olympian gods. The interior is no less impressive with magnificent vaulted ceilings, paintings, sculptures, murals and frescoes - especially the giant, florid tribute to a Hapsburg victory in the Grand Hall. After major reconstruction of the house and garden in 1998, the Chateau became an annex of the City Gallery, housing a collection of Baroque glass and a collection of 19th century Czech paintings. Troja was hard hit in the 2002 floods, but the gardens and house are back in their former glory. From the metro, hop on tram 5, 17, 25 to Trojská or bus 112 to the Zoo.

Admission 120/60Kč, gardens free.
