Along the old road that leads from Tuoro to Tuscany is the ‘Dogana’ (the former Customhouse), a sixteenth-century building with a large loggia on the ground floor that reminds us of the border between the State of the Church and the Grand Duchy of Tuscany. The building served both as a coaching inn for the changing of horses and for the control of goods in transit to discourage smuggling.
A plaque marks the passage of illustrious guests: Byron, Galileo, Goethe, Michelangelo, Stendhal. Old legends, with a probable foundation of truth, also tell of a place where criminals carried on their trade.

After the unification of Italy, the building was transformed into a manor house completely frescoed by Count Papi.
