Pisa's baptistery is Italy's largest: a marble cylinder over a hundred metres round, its dome outtopping the leaning tower itself — begun Romanesque (1152) and finished Gothic by the Pisano family, the two styles reading as embracing storeys, its odd double dome (a half-cone inside a cupola) the secret of its living wonder. The wonder is the echo: the double dome holds sound ten full circling seconds — so a custodian stands at the font each half hour and sends up successive notes that stack into a choir from a single throat: the world's most famous architectural sound show, three notes enough to shiver the hall. And it holds Nicola Pisano's pulpit (1260) — Renaissance sculpture's founding moment two centuries early: Rome's classicism waking on Gothic supports. Climb the upper gallery to face the cathedral façade at bird's height.

Almost certainly a constructional accident, not design — but Pisa has made it daily art for centuries.
Golden-century pride: victorious Pisa wanted each monument the largest — its baptistery outdoing its own cathedral dome, rivalling Byzantium. Then the fleet broke before Genoa (1284) and the golden time stopped — leaving the field like its ambition: complete at the edge of the breaking.
