Burg Castle history
Between 1218 and 1225 Burg Castle was greatly enlarged for Count Engelbert II of Berg. The new two-storey hall was built, and the castle was strengthened with the walls of the outer bailey. The new castle chapel was also built.
During the Thirty Years' War, Swedish troops laid siege to the castle in the autumn of 1632, when it was under imperial garrison. However, Swedish troops failed to capture Burg Castle. However, it was heavily damaged by incendiary devices and cannonballs. After the conclusion of the peace treaty in 1648, the imperial troops destroyed large parts of the fortifications before they left.
Between 1887 and 1895 the castle was restored. The castle contains the Burg Castle Museum.
