The Palace's structure is very particular for its "C" form. We cross Street Torre and we admire the central body of the construction, built with bricks at sight, while the two leaning sides have been plastered and restructured. At the center of the facade there is an arc sustained by cylindrical columns. Above the arc there is a balcony with a handrail of beaten iron. The bricks, that form very simple (horizontal and vertical lines) reliefs, decorate the facade and highlight the high windows. The Marquis Castelli, in the second halves of '600, began his construction, which has never finished. The building is high, with four floors, two lower  used by the servitude, two taller used by the Lords. Around 1860 it was destined at working house. Then it was neglected. Its architecture and its dimensions excited the imagination of the people, that wrongly believed it the old leftover of a castle or a tower. In this way it was born his surname, the tower. It has been modified in the time and recently restructured. We come back to our steps and, at the corner between Street Torre and Street S.Michele, on the facade of the building which entertain the electronic shop, we meet a mural painting.
