The facade of the church of Sant’Isidoro a Capo le Case stands as a primary example of how Italian architecture transitioned from the borrominesque style toward the Roman rococo. Constructed between 1704 and 1705, this project utilized an existing portico and staircase to demonstrate the evolving aesthetic sensibilities that defined the early 18th century in Rome.
