Monks from Sienna from the order of The Blessed Giovanni Colombino established themselves here in 1392. In 1423 they built an oratory and cloister dedicated to Saint Jerome. (They had previously occupied the nearby church of Sant’Agnese.) A proper church and monastery were built here by the Poor Gesuati order (as they now called themselves) from 1494, consecrated 1524 and dedicated to Our Lady of the Visitation. The order was suppressed in 1668 and in 1669 the Dominicans bought the place and got Giorgio Massari to build the present, much larger, church, beginning work in 1726, to the east of the old church, and finishing it in 1743. Massari also converted the old church (Santa Maria della Visitazione) to a library. The newer church became a parish church when the order was suppressed in 1815, to replace the nearby suppressed churches of San Vio and San Gregorio. The monastery to the left of the church, which become a boys' home after suppression, is now the home of the Istituto Don Orione.
