The largest courtyard inside the castle is known as ‘Piazza Grande’. It is dominated by the Count’s Palace, through a large loggia located at the middle bastion. It encloses service spaces, including the ‘Clock Tower’, the ‘Powder Magazine’, and the remains of the so-called ‘Stables’.

A room overlooking the Court of Honour, probably near the kitchens, is characterised by the presence of a large oven once used for baking bread.

A ground-floor room houses a stone well from which it was possible to draw water collected in an underground cistern carved into the rock. The channel that conveyed rainwater from the gutters into a basin with a filter, and then into the cistern, is still visible and functional today.

On the second floor of a partially destroyed building, the room retains traces of a pictorial decoration from the Renaissance period. The frieze, traditionally referred to as a representation of the Months, depicts a vast and deep mountain and rural landscape populated by wayfarers and peasants

Adjacent to the Count’s Palace, the middle bastion preserves traces of residential spaces reachable by an imposing staircase. Today this area, now a garden, is closed on one side by a portico overlooking Piazza Grande

The south bastion is equipped with standard defensive features but also houses a niche with stone seats, elegantly frescoed.
From here, one can view the southern area of the Adige plain. Looking out from the embrasures, Castel Pietra can be seen. Together with Beseno Castle and the castles of Nomi and Barco on the right bank of the Adige, it formed part of the defensive system protecting the imperial borders of the Prince-Bishopric of Trento.
