In the years 1375-1466, lists of inventories were carried out in Torun, from which we can find out today that there were: a cloakroom, an armory, a crossbow room, a commander’s stable, a mill, a cellar, a conventual cellar, and a commander’s cellar. Liturgical equipment and food were stored: grain, meat, salt, and fish. The interiors of the castle were equipped with heating and sanitary installations, providing maximum comfort.
Probably in the second half of the 14th century, on the eastern side of the castle, in the marshy area behind the dansker, a dyke was built, and with it, a gate called the coinage. The construction of the dike allowed for the damming up of water and the creation of a pond called the commander’s pond. In addition to the commander managing the entire territory, in the Teutonic castles there was also a vice-commander, the so-called house commander dealing with the administration and supply of the castle itself. The remaining religious brothers shared various functions among themselves, such as a cellar, mint master, gardener, manager of the armory, mills, forests, etc. The administration of the order was centralized and extremely bureaucratic. The Teutonic Order’s books of accounts that have survived to this day prove that the offices of the convents kept reporting and accounting at a level unprecedented in Europe. The Torun castle was one of the most important strategic points of the monastic authority.
