The very diverse collection areas in today's Thuringian State Museum Heidecksburg comprise a variety of outstandingly crafted objects. Some of these collections have grown historically, for example the castle library, the »Schwarzburg Armoury« weapons collection or the sculpture collection. The allocation of further arts and crafts collection areas came about when the holdings of the Castle Museum, the Natural History Museum and the Local History Museum were combined in 1950 with the formation of the State Museums Heidecksburg and the inventory process that began in the subsequent years.
In addition to furnishings, utensils and everyday objects from Heidecksburg Palace and Schwarzburg Palace, the arts and crafts collections also include individual representative objects from the personal estates of the Princes of Schwarzburg-Rudolstadt. From their multifaceted passion for collecting, the most diverse collections have survived to the present day.
