Rome Reopens Borromini’s Sant’Ivo alla Sapienza After Major Restoration

Rome’s Sant’Ivo alla Sapienza, the 17th-century church designed by architect Francesco Borromini, reopened to the public on Tuesday after an extensive restoration that lasted several years.

The restoration, overseen by Italy’s Ministry of Cultural Heritage, addressed structural cracks, cleaned the marble façade, and restored the iconic dome’s intricate geometry. The work also included the conservation of interior frescoes and the replacement of deteriorated stone elements.

Italian art historian Giulia Giuli said the church now stands as “one of the most extraordinary testimonies of Italian creative genius,” highlighting its significance in Baroque architecture.

Visitors can once again access the church’s unique oval plan and the famous corkscrew lantern that crowns the dome, features that have drawn scholars and tourists alike since the building’s completion in 1660.

Restoration Details

The project, funded by the European Union’s cultural heritage program and the Italian state, began in 2020. Specialists used laser scanning to map the dome’s complex curvature, enabling precise stone replacement. Conservation teams removed centuries of pollution deposits from the exterior, revealing the original white travertine.

Inside, frescoes by Giovanni Battista Passeri were cleaned with solvent‑free techniques to preserve pigment stability. The wooden choir stalls, damaged by humidity, were repaired and re‑treated with historically accurate finishes.

Historical Context

Sant’Ivo alla Sapienza was commissioned by Pope Innocent X for the University of Rome’s former Sapienza campus. Borromini’s design broke with conventional church layouts, employing a centralized plan that integrates the dome with the surrounding arches.

Architectural historians consider the church a masterwork of spatial innovation, influencing later Baroque and modernist architects.

Guided tours are scheduled to resume next week, and the site will host a series of lectures on Baroque architecture later this month.
