The ends of the rafters are supported by beautifully carved consoles.

All the woodwork is stained dark brown, and here and there on the ceiling are wooden shields, on which are painted the Borgia arms in colors.
In various places in the interior, and also without, on the towers of the stronghold, the same arms may be seen carved in stone.

There are also two stones, with the arms very carefully chiseled, set in the walls of the entrance hall of the town house of Nepi, which were originally in the castle where they had been placed by Lucretia's orders.

The Borgia arms and those of the house of Aragon, which Lucretia, as Duchess of Biselli, had adopted, are united under a ducal crown.
Lonely Nepi, which now has only 2,500 inhabitants, had but few more in the year 1500.

It was a little town in Campagna, whose streets were bordered by Gothic buildings, with a few old palaces and towers belonging to the nobles, among the most important of whom were the Celsi.
