Collegiata di Sant'Andrea, Collegiate church in Empoli, Italy.

The Collegiata di Sant'Andrea is a Romanesque collegiate church in the historic center of Empoli, with a facade covered in white marble and green serpentine stone arranged in geometric patterns. The front features five blind arcades and decorative panels that reflect the style of medieval Florentine architecture.

The first secure record of the pieve is a bull of Pope Nicholas II from 11 November 1059, addressed to the parish priest Martino. In December 1119 Countess Emilia, wife of Guido Guerra, granted the priest Rolando and the inhabitants the right to build houses and defensive walls around the church, the founding act of Empoli. A Gothic rebuilding began in 1389 under Pietro di Ugucciozzo de' Ricci; the upper facade was redone to Carlo del Re's design by 23 January 1803.

The church is named after Saint Andrew, the patron saint of Empoli, and remains a gathering place for local community life. Concerts are regularly held inside, bringing together sacred music and classical performances in a setting that has shaped the town for centuries.

The church sits in a visible spot in the historic center of Empoli, making it easy to reach on foot from most points in the old town. Morning or early afternoon light brings out the details of the marble cladding, so these times work best for a close look at the facade.

The lower facade is the only surviving Romanesque portion of the church, and its white marble panels are 7 to 8 cm thick, thick enough to serve a structural role rather than just a decorative one. An inscription between the two orders helps date this facade and the whole Florentine Romanesque style.
