Joanna I of Naples
On 30 April 1351, Queen Joanna I of Naples and her husband Louis of Taranto had Monticello, along with the neighboring communities of Ponzano, Varano and Tofo Sant'Eleuterio, incorporated into territory (at that time referred to as a Università) of Teramo. In 1368 the nearby Campora was added to this list. Norman feudal records show Monticello and nearby Nepezzano under the tutelage of the Melatinos, a powerful family who dominated the area around Teramo, up until the 15th century.
