Sant'Agnese in Agone, Baroque church in Piazza Navona, Rome, Italy
Sant'Agnese in Agone is a baroque church on Piazza Navona featuring a concave facade with twin bell towers and a central dome. The interior displays elaborate marble decorations and frescoes that reflect the elegant baroque style of the building.
The church was commissioned by Pope Innocent X in 1652 to replace an earlier structure at the site of Saint Agnes martyrdom. The project followed the family pope's establishment on the square and was shaped by leading baroque architects of the time.
The name 'in Agone' comes from the ancient Stadium of Domitian, called 'agone' for its athletic contests. The church hosts regular classical concerts in the Borromini Sacristy, ranging from sacred Baroque works to chamber music and operas. In the crypt, a marble relief by Alessandro Algardi shows the Miracle of Saint Agnes' Hair.
The entrance is on Piazza Navona, under the central portal of the concave facade; the interior is a Greek cross around a central octagon, so the four altars and two transept chapels are seen in one circuit. The crypt, made from a medieval oratory, is reached separately and was restored between 2017 and 2026. The church also serves as a concert venue, with classical works performed in the Borromini Sacristy.
The church stands at the exact spot of Saint Agnes execution in the ancient Domitian stadium, which determined the curved shape of Piazza Navona. This archaeological link between ancient Rome and Christian history makes the square a crossroads of two eras.
