The monumental Baroque state chateau of Duchcov, built on the site of an earlier Renaissance residence, is known worldwide as the place where the famous Giacomo Casanova worked as a librarian towards the end of his life. Visitors can take guided tours featuring the rich collections of the Wallenstein family gallery, historic furniture and an exhibition dedicated to Casanova himself. Adjoining the chateau is an extensive princely park with a pavilion housing the famous fresco by Václav Vavřinec Reiner. Cycling is prohibited throughout the chateau park, but cyclists can safely lock their bikes in the racks located right in front of the entrance to the main courtyard.
