Currently the villa bears the name of the founder (Costanza Caldera of Bergamo) of the religious institute that has owned it since 1953: the Pie Madri della Negrizia. The Saibante were the owners from the end of the 16th century until the beginning of the last century, leaving the property due to extinction of the branch. The Monga later took over. The structures visible today can be dated to the first decades of the 17th century. The building has an inverted 'U' shape with two facades. The main one has a main body and two wings perpendicular to it; the one facing north looks at a fountain with a marble group. On the ground floor there is a portico that runs along the three sides of the building. The west wing, which already incorporated some cottages, was later raised, while in the late 1700s it was probably used as stables. The windows on the main floor are rectangular, while the center of the façade juts out with three large windows decorated by a nun of the institute. The courtyard is closed by a low wall containing six mythological statues preceded by two tuff lions. Inside there is a well from 1623. Inside the building there are two large halls: one, with terracotta floor and coffered ceiling, the other in the central body and overlooking the courtyard, has a decorated stucco ceiling and walls frescoed with landscapes. Today it is used as a chapel. In the first hall, decorated with frescoes by the Veronese Paolo Ligozzi (1629), high pedestals support two telamons bearing two Ionic capitals on which the ceiling beams rest. Paintings of leaders and representations of the continents are inserted respectively in false niches and in the over doors. Little remains of the ancient garden: the fountain and an artificial grotto. The park was devastated by the Germans during the Second World War. There are still some architectural pieces deriving from the Andrea Monga collection.
