The castle is first mentioned in 1318 and following a fire in 1573 was rebuilt in the Renaissance style. In the second half of the 16th century a Czech Brotherhood school was founded at Košumberk to educate young Protestant nobles (later including, among others, the famous warrior Albrecht of Waldstein). In 1684 Košumberk passed into the ownership of the Jesuit college in Hradec Králové, which established its residence next to the pilgrimage church. After the abolishment of the Jesuit Order the domain was administered by the church foundation; in 1826 it passed into the ownership of the Thurn-Taxis family. Today the structure is owned by the town of Luže.
