Ordensburg
Ordensburgs were fortresses built by crusading German military orders during the Middle Ages.Medieval Ordensburgen
The Ordensburgs were originally constructed by the Livonian Brothers of the Sword and later the Teutonic Knights to fortify territory in Prussia and Livonia captured from the native populations - Old Prussians, Lithuanians and native peoples of what is now Latvia and Estonia. Later, Ordensburgs were used to attack Lithuania. Since they were built and used by religious military orders, the Ordensburgs often resembled cloisters. While they were considerably larger than those in the Holy Roman Empire, they were much scarcer in the Monastic state of the Teutonic Knights. While a normal castle in the Reich would control about 38 km2, a castle would control 370 km2 in Prussia and 789 km2 in Livonia, Courland and Estonia. The few small castles are considered to be of vassals, while the larger ones might have served as arsenals and strongholds during the Northern Crusades and were purpose-built to colonize the respective countries and peoples by capturing territory, forcefully imposing the Christian religion and extracting economic value via looting, genocide and enslavement of the native peoples.
Most Ordensburgs were rectangular, even quadratic in form, built from red brick and lacking a Bergfried. Many castles had no towers at all, as the bailey, a mighty quadrangle, was considered sufficient for defence.List of medieval Ordensburgen
