From the then medieval castle, only a dilapidated little tower is visible in the castle today.

The present form of Castel Nanno dates back to the wish of the Prince-Bishops Madruzzo, so it was rebuilt for summer stays in the middle of the 16th century. As a result, only little of the original castle can still be seen today. The square arrangement with the four corner towers surrounds the main tower in the middle.
Even if the atmosphere that surrounds the castle today seems very quiet, in the past Castel Nanno was the scene of dramatic events: legends say that terrible witch trials took place here. Even today, an inscription on a truncated column commemorates these times in the 17th century.
Today Castel Nanno can only be visited from the outside and is privately owned.
