 Again in 1576, the Duke was given an oath of loyalty from Antonio Brancaleoni.After the male lineage of Brancaleoni ended, on 25 May 1729, the church took judicial control from the Brancaleoni family for just three years - after this, a papal bill extended the rights to Piobbico to the female line of the family - it thus stayed in the family's control until 1816.The town is known as the host to the "Festival of the Ugly", which is organized annually by the World Association of Ugly People and held on the first Sunday in September.
