The day after the pastoral visit of Charles Borromeo in Brugherio (to establish the church of Saint Bartholomew) in 1578, the archbishop visited the church of Saint Margaret in Baraggia, which was then attached to the house of Giovan Battista Bernareggi (now Villa Brivio).

The church consisted of an arched chapel, a separated altar which did not follow canonical rules, and a round window on the front.

The balustrades of the presbytery and the sacristy doors (made of painted wood and imitation marble) alternating with one another, make the interior regular-shaped.

This painting is thought to replace a previous one (portraying Saint Margaret with the palm of martyrdom), which is now placed on the left wall of the nave.

[3] The exterior of the church is simple: its façade is gabled, with prominent cornices in its mid and top portions.
