Under the rule of Charles IV, the salt and grain warehouses were founded, and were the largest in Bohemia. For centuries, the town of Písek was the holder of the largest urban estate in Bohemia, especially forests.

During the Hussite Wars, Písek was conquered by the Hussites and the monastery was razed. During the Thirty Years' War in 1619–1620, the town was conquered and most of its inhabitants killed by the army of Charles de Longueval, Count of Bucquoy. In 1623, Písek was acquired by the royal chamber again, and in 1641, it was once again promoted to a royal town. In the 18th century, it became the centre of Prácheňsko again.
