Why go
Start at the doorway facing the Cathedral, where carved scenes introduce St John the Baptist. Inside, the octagonal font and Nicola Pisano's sculpted pulpit give the otherwise spare room its focus. The double roof creates the remarkable acoustics described by the monument operator, a reason to step inside if it is open.
What to look for
- Rounded arches below and pointed Gothic details above show the building's long construction.
- The doorway facing the Cathedral carries scenes from the life of St John the Baptist.
- Nicola Pisano's pulpit stands near the octagonal baptismal font in the spare interior.
The full story
The Baptistery of San Giovanni was founded in 1152, with Diotisalvi named in the early design. Its long building period is visible outside. Rounded Romanesque arches give way to pointed Gothic forms above, while the marble doorway facing the Cathedral sets scenes from the life of St John beside images of Christ, Mary and the evangelists. Inside, the decoration becomes much sparer. The octagonal font, made in 1246, marks the building's purpose, and Nicola Pisano's pulpit draws attention to the human forms carved in its narrative scenes. The roof also shapes the experience: an inner pyramidal structure sits beneath the outer dome, creating the pronounced resonance described by the monument operator. These details reward a circuit of the exterior before entering. The building is both a working part of the square's religious sequence and a record of changing medieval taste.
Useful to know
- Compare the Baptistery's exterior with the Cathedral before going inside.
- Check the operator's current calendar for entry.
