Glatzer Kessel
The complex is located on the heights of the Sudety Mountains, a body which forms a natural border between the Kłodzko Valley and the Silesian Lowlands. It controls the passage through the Silver Valley (Polish: "Przełęcz Srebrna", German: "Silberbergpass"). The fort spans three hills: Ostróg (627 meters above sea level), Warowna Góra (686m), and Wielki Chochoł (740m). The fort could shelter a garrison of 4000 soldiers, supplied to survive a year-long siege. It was defended by 264 artillery pieces. The fortress was intended to guard a route linking Prussian territories with Bohemian lands in the south, and thus help repel any possible incursions from Austria. The cost of the construction was reported as 4.5 million Prussian thalers.
