Not far distant stood their old castle, the Torre di Nona, which had originally been part of the city walls on the Tiber.

At this time it was a dungeon for prisoners of state and other unfortunates.
It is not difficult to imagine what Vannozza's house was, for the Roman dwelling of the Renaissance did not greatly differ from the ordinary house of the present day, which generally is gloomy and dark.

Massive steps of cement led to the dwelling proper, which consisted of a principal salon and adjoining rooms with bare flagstone floors, and ceilings of beams and painted wooden paneling.

The walls of the rooms were whitewashed, and only in the wealthiest houses were they covered with tapestries, and in these only on festal occasions.

In the fifteenth century the walls of few houses were adorned with pictures, and these usually consisted of only a few family portraits.
