Fodor's Expert Review Trojský zámek
Built in the late 17th century for the Czech nobleman Count Šternberg, this sprawling summer residence, modeled on a classical Italian villa, had the first French-style gardens in Bohemia. Inside, rich frescoes that took more than 20 years to complete depict the stories of emperors. Outside, there's plenty of pomp and ceremony, with a red-and-white baroque façade and a sweeping staircase adorned with statues of the sons of Mother Earth.
The château is closed from November through March.
