Pieve di San Lorenzo, Romanesque pieve in Borgo San Lorenzo, Italy.

Pieve di San Lorenzo is the main church of Borgo San Lorenzo, in the Mugello north of Florence. The present building results from a 12th–13th-century reconstruction: three naves on columns and square pilasters end in a single large semicircular apse, whose capitals carry angular volutes and stylized leaves. The terracotta bell tower, of irregular hexagonal plan, rises on the apse with five tiers of single and double openings.

The pieve is recorded in a document of 934, and the present church results from a rebuilding of the 12th–13th centuries. Its irregular hexagonal terracotta bell tower rises on the apse, with five superimposed levels of single and double openings. Six bells in E-flat, cast in 1826 by the Prato founder Santi Gualandi, hang at the top; the largest weighs about 1,400 kg.

The counter-facade holds Piero di Cosimo's panel of the Madonna and Child with Saints John the Baptist and Thomas, painted around 1510-1515 for the Confraternity of the Madonna, called the Azzurri after their oratory annexed to the pieve. The Pentecost beside it is by Jacopo Vignali. On the right nave's second altar, Cesare Velli's signed Deposition of 1592 was commissioned by Francesca, widow of Giovanbattista Cocchi, in his memory.

The church stands in the centre of Borgo San Lorenzo, in the Mugello north of Florence. Visitors enter from the street side; the irregular hexagonal terracotta bell tower rises above the apse and is best seen from outside. The interior is on one level with three naves, so the side altars and pillars can be visited in sequence.

The hexagonal terracotta bell tower rises on the apse and opens through five stacked levels of single and double windows. At its top hang six bells in E-flat, cast in 1826 by the Prato founder Santi Gualandi; the largest weighs about 1,400 kg. Each bell has its own name: la Grossa, la Misericordia, la Terza di Sù, la Terza di Giù, la Danda and la Piccina.
