King Ottokar II of Bohemia replaced it by a stone castle, which became the seat of the Lordship of Poděbrady.
When in 1350, Hynek's daughter Eliška married Boček I of Poděbrady (d. 1373), the castle came into the possession of the Kunštát family.
Between 1548 and 1580, it was reconstructed to a Renaissance style, after a design by Giovanni and Ulrico Aostalli and Hans Vienna.
Under her son Joseph II, the castle was the residence of retired Imperial Army officers.
In 1839, the Crown sold the Castle and the Lordship to the Viennese banker Georg Simon Sina (1783–1856).
