Carlo Rainaldi

Carlo Rainaldi (4 May 1611 – 8 February 1691) was an Italian architect of the Baroque period.

He worked at first with his father, Girolamo Rainaldi, a late Mannerist architect in Rome.

He gained ascendancy in Rome when the Barberini pontificate of Pope Urban VIII was replaced by that of the more austere Pamphilj papacy of Innocent X.

[2] Beyond his work as an architect in stone, Rainaldi also designed stage sets for religious rituals and events.

In 1650, he designed the sets for the Quarant'ore, or Forty Hours Devotion, held in the church of Il Gesù.
