Antonio De Petri (or Petro), parish priest from 1778 to 1819, took inspiration from Antonio Francesco Frisi's works, called ''Memorie storiche della città di Monza'', and wrote a report about saint Bartolomeo's church<ref name=":0">{{Cita libro|autore = |titolo = Brugherio la nostra gente|anno = |editore = |città = |p = 145}}</ref>:
{{Citazione|<nowiki>The church's façade is decorated with cornices, pilasters and bands with a pediment gabled sharp that befits the structure itself.

In addition, continuing in the description, the De Petri reports the presence of a number of paintings, including one depicting the Martyrdom of Saint Margaret, the seventeenth century<ref>{{Cite book||title = San Bartolomeo: una ricostruzione storica delle vicende della parrocchiale|language=Italian||p = 24}}</ref>.
In this period was also built the current bell tower.
