In 1633 the Ghetto Novissimo was added to the existing two ghettos, mainly for the purpose of accommodating Ponentine Jews. Situated at the confluence between the San Girolamo and Ghetto Novo canals, it is the smallest of the three. The area was formed of three blocks of houses, with fine buildings (such as the Treves and Vivante palaces), but did not contain shops or scole. At the end of Calle del Portòn was the gate, which was kept closed.
