On the site of the ancient walled house, the first bishop’s property within the castle, the building commissioned by Bishop Prince Georg von Liechtenstein was developed at the end of the 14th century. Its original appearance is shown on the month of January in the famous frescoed Cycle of the Months in the Torre Aquila in Trento.
On the ground floor are the cellars, atmospheric spaces now used to display the rich collection of keys and locks from the medieval period to the 19th century. On the first floor, accessed through the Palazzo Hinderbach, is the old kitchen, with its large fireplace, decorated with furniture and tools made from copper and wood. On the second floor is the Medallion Room, so called because of the elegant 16th century pictorial frieze in which allegories and personifications of the virtues face each other through fake oculi, created by a painter commissioned by Prince Bishop Bernardo Cles.
