Cascina Caldera dates back to 1500 and was owned by the Rainoldi nobles until 1596. The name "Caldera", a toponym of dialectal origin ("boiler"), derives from the morphology of the place in which it stands: here in fact there is a depression in the land round shape.

It is located within the Cave Park, the second largest in the city, in which the exploitation of gravel quarries continues respecting the customs and traditions of life in the fields. It is no coincidence that the Caldera is one of the few farms that still uses water from a fountain - a typical water source of the Po Valley - to irrigate the land and to carry out cultivation and livestock farming functions.

In 1608 a small church dedicated to San Carlo Borromeo was built inside the farmhouse, then demolished to widen the entrance to the courtyard and increase the spaces dedicated to the breeding of cattle, pigs and chickens. In that same year, at the entrance to the farmhouse, on the left wall, a plaque in Latin was placed in memory of the pastoral visit that San Carlo Borromeo made in 1576 to the farmhouses of the Pieve di Trenno.

Inside the Cave Park, in the Cascina Linterno, there are two typical Lombard water meadows placed under environmental protection.

Not far away, in via Novara, the building that housed the headquarters of the old municipality of Trenno survives, united with that of Milan together with other small municipalities in 1923.
