The church is placed in a co urtyard setting, it is one of the masterpieces of the architect fromTicino.The commission to complete the construction of the building was given to Borromini by Urban VIII on the advice of Gianlorenzo Bernini in 1632. In the following years, the architect planned the church, or the university chapel, which was dedicated to St. Ivo, protector of the consistorial Iawyers and generous helper of the poor. The facade coincides with the exedra by Della Porta. Borromini added the attic to this with the mounts, the emblems ofAlexander VIl, the pontiff who consecrated the church.

The facade is characterised by the famous Iantern finishing in a spiral that seemed to want to screw into the sky. Both the exterior and the interior are completely white. The central plan, in the form of a hexagonal star, is created by the interpenetration of two equilateral triangles. The walls are decorated with architectonic items alternating with niches that were originally aimed at holding statues. The dome divided into segments, is decorated with rows of stars, cherubs, Chigi mountains, and laureI wreaths, culminating in the dove of the Holy Spirit.The entire decoration, interior and exterior, exalts the theme of divine knowledge
