What should you know before visiting Pisa Baptistery (Battistero di San Giovanni)?
Rising opposite the Cathedral in Piazza dei Miracoli, Pisa's Baptistery is the largest in Italy. Construction began in 1152 in austere Romanesque style, but when Gothic fashion arrived a century later, architects added pointed arches and elaborate decoration to the upper levels -- the result is a unique fusion visible in the building's profile. Two features make this baptistery unforgettable. First, the extraordinary acoustics: the dome creates a resonance that allows a single voice to harmonize with itself. Guards demonstrate this phenomenon every 30 minutes, and the effect is genuinely magical. Second, Nicola Pisano's hexagonal pulpit (1260) revolutionized sculpture by reviving classical Roman techniques -- it is considered the birth of Renaissance sculpture, 150 years before Florence's Renaissance began. The Leaning Tower stands alongside.
