As was typical of the houses of noble families in this era, the Gatti Palace included defensive towers, six in number, that no longer exist. The palace is said to have hosted a number of visiting lords, including in 1328 Louis IV, Holy Roman Emperor (Ludovico il Bavaro); in 1452 Frederick III, Holy Roman Emperor on his way to Rome to be crowned by Pope Nicholas V and to receive his bride to be, the young Portuguese princess Lionora; and also in 1474, Federico da Montefeltro, Duke of Urbino.
