Baptistery of St JohnBattistero di San Giovanni

Baptistery of St John, begun in 1152 on Pisa’s Piazza dei Miracoli, gave the maritime republic a monumental setting for the rite that marked entry into Christian life. Its circular, striped-marble shell shifts from Romanesque weight to Gothic lift as construction stretched across the 12th–14th cc., mirroring a city at its zenith. Inside, the resonant dome turns sound into ceremony, while Nicola Pisano’s marble pulpit (c. 1260) revives Classical form and signals a turning point toward Renaissance sculpture.
