It is a 14th century palazzo built around a wide portico courtyard. The medieval body of the building facing Trecchi Street has remained intact.

The most important cycle of medieval paintings in a private residence is represented here.

In numerous halls, some of which are wholly frescoed, one can admire 14th and 15th century decorations concerning such themes as human figures, animals, vegetable images with coats of arms, rosettes, starried tapestries, niches, architecture following the international Gothic style.

These frescoes are a superb document of Lombard taste shown in noble palaces, as they reflected the influence of the Visconti court, to which Cremona was subdued since 1334.

The palace was also the main residence of Count Ugolino Cavalcabò, leader of the Guelph party and in power of the city from 1403 until his death.
