The Kostelec nad Černými lesy Castle is the main landmark of the town. The castle was first documented in 1348. Until 1549, when it was destroyed by fire, the castle served as a hunting lodge of Emperor Ferdinand I. After 1550, it was rebuilt in the Renaissance style. After 1750, baroque modifications were made. Today the castle is owned by Czech University of Life Sciences Prague and is used for social and business purposes. The neighbouring Church of Saint Adalbert is connected with the castle by a covered corridor.
The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
