The castle from the end of the 13th century was built in the place of an old fort.
Since 1359 Nové Hrady were owned by the Rožmberks who had it fortified and convert into an oval form.
Another lagre conversion was performed in the first half of the 17th century when apartments for the officials were built within the castle.
Since the second half of the 19th century it was the seat of a forest administration office.
At the beginning of the 19th century an Empire chateau was built in the town.
