Libochovice Chateau is the birthplace of the world-famous Czech naturalist and physiologist Jan Evangelista Purkyně (1787–1869). A separate exhibition is devoted to this most important citizen of Libochovice on the ground floor of the chateau. Purkyně had returned to Libochovice everytime and even Libochovice never forgot his famous character. Monument to J. E. Purkyně was placed in front of the entrance to the chateau in 1887.
