Hidden in the porticoed courtyard of Palazzo della Sapienza , this tiny church is a masterpiece of baroque architecture. Built by Francesco Borromini between 1642 and 1660, and based on an incredibly complex geometric plan, it combines alternating convex and concave walls with a circular interior topped by a twisted spire.
Palazzo della Sapienza, seat of Rome’s university until 1935 and now home to the Italian state archive, is often used to stage temporary exhibitions.
