Conceived by Taddeo Barberini, relative of Pope Urban VIII Barberini, this semi suburban palace has an unusual U-plan, with an extended arm and no interior courtyard. While this was common in the designs of other suburban Roman villas, for example Villa Farnesina, Palazzo Barberini was seen as an innovation and fit into the Early Baroque genre. Carlo Maderno was involved in the replacement of the pre-existing Villa Sforza, he worked on this project from 1627 to 1629, when he died. He was replaced by Gianlorenzo Bernini (1598-1680) and Francesco Borromini (1599-1667) was to be his assistant. Featured here:
- 2 story hall with an oval salon
- 3 tiers of arch headed windows
- Borromini's arcade windows on top story, these were set in using perspective to suggest depth
- superimposition on main facade, loggias facing street
- 2 staircases, one by Bernini and another more interesting oval staircase by Borromini
The interior was decorated with exuberant frescoes by Pietro da Cortona. Bernini finshed the Palazzo in 1638.
