The courtyard in the 15th century
The various chambers in the Ducal Palace were structured around the courtyard. But in the 15th century there a footbridge that crossed over the courtyard in order to connect the chapel (east wing) to the front part of the Palace (west wing).
This bridge – which was destroyed in the 1st half of the 19th century – leads to the belief, by comparison to other Palaces of the same period, that there was a loggia (a covered exterior gallery) in the front part of the Palace.
