Srebrna Góra Fortress (Festung Silberberg), the largest mountain stronghold in Europe, was built very quickly - in just 12 years (1765–1777). The project was designed by the Prussian engineer Ludwig Wilhelm Regler and modified by King Frederick the Great himself. The fortress consists of six forts located on two hills, with a donjon - the largest structure of its kind in Europe. It was self-sufficient and prepared for a prolonged siege, equipped with 264 cannons and accommodations for over 3,700 soldiers.
