The former monastery of the Poor Clares of Cerreto Sannita is an ancient place of worship founded in 1369 by Francesca Sanframondi, collateral and chamberlain of Queen Giovanna I of Naples and relative of Giovanni III Sanframondi, Count of Cerreto Sannita. Rebuilt after the earthquake of 5 June 1688, the monastery housed the Order of the Urbanist Poor Clares from the 14th to the 20th century when it became the property of the Sisters of Charity of Our Lady of Good and Perpetual Help who established a boarding school, a nursery school, a language school, a school and a master school, naming the plexus after Pope Leo XIII. The church attached to the monastery is a splendid example of Baroque architecture.
