Lead sheeting and tiles meet on the surface of the double dome of the Battistero di San Giovanni (Baptistery of St. John) on the Campo dei Miracoli in Pisa, Tuscany. The dome was added in the 1300s by Cellino di Nese to a building started in 1152. It is a double dome, with an inner dome of truncated cone shape and an outer hemispherical dome.


Pisa, Tuscany, Italy: double dome of the Battistero di San Giovanni (Baptistery of St John) on the Campo dei Miracoli. The vault of the baptistery consists of a double dome – the inner one a truncated cone and the outer one a hemispherical dome. This singular architectural solution gives the baptistery exceptional acoustics. The Baptistery of San Giovanni was founded on 15 August 1152. Its basic shape and design of the lower part of the building was established by Diotisalvi, who supervised its construction from 1152 until about 1180. The inscription “Deotisalvi magister huius operis”, “Deotisalvi is the architect of this work”, appears on a pillar. Solemn ceremonies, such as the investiture of the Operaio del Duomo, were already being held here in 1185. Towards the mid-1200s the Baptistery building site was again a hive of activity: while Guido Bigarelli da Como worked inside on the baptismal font, work on the outside started again under Nicola Pisano, together with his son Giovanni, who introduced sweeping changes to Diotisalvi’s structure. Nicola, an architect and sculptor, also made the pulpit (1260), which immediately became a model for others; in the 1300s the external loggia was adorned with sculpted figures by Nicola’s son Giovanni. It was here, at the Baptistery building site, that the “Renaissance” of sculpture began, with the work of Nicola Pisano and later of Giovanni. It represented the moment when “mediaeval” became “modern”. The building displays a mix of Romanesque and Gothic styles. Here, in 1564, Galieo Galilei was baptized.
