During the renovation works of mid-17^th century, Architect Paolo Marucelli kept its original structure, with the six columns erected at the time of Pope Leo X.

The 6^th-century Church of San Salvatore in Thermis was adjacent to the courtyard. In the decades between the 19^th and 20^th century it was first closed, then expropriated and finally pulled down to extend the building towards St. Louis de France Square. The church had been closed in 1894 after a bombing attack against the Chamber of Deputies, because the police feared it might be used as a base for a similar attack against the Senate.

The Staircase of Honour can be seen to the left of the porch. At least a part of it was rebuilt by Marucelli on the basis of the original 1509 plan. The ancient floor in travertine was replaced by a marble one.

A statue by Emilio Greco was placed in the centre of the courtyard in 1972.
