Located in the Piazza dei Miracoli (Miracle Square), on the west coast of Italy, the Baptistery of Pisa forms one of the four buildings. In fact, it comes second in the chronological order, neighboring the Duomo di Pisa, the cathedral, and the Leaning Tower of Pisa.
It is an ecclesiastical building, and throughout history, it has played a keen role in the religious scene in Pisa. This actually shows in the multiple architectural veils that it is draped in. The lower side has arches and pillars that hint towards the Romanesque style, but the upper levels show a stark Gothic style with pointed figures and closely spaced pillars.
The entrance to the edifice is covered with ornate pillars and reliefs, in which the upper one depicts the life of Saint John and the middle one shows Christ flanked by Saint John and Madonna and surrounded by several angels.
The Baptistery of Pisa – Where Galileo Was Baptized
This baptistery is famous for its architecture and also for the following things.
1. The Acoustics: Nicola Pisano and his son Giovanni Pisano have done an outstanding job by designing the interior that it facilitates reverberations or acoustics. Anyone standing below the edge of the dome can have his voice echoed. Every 30 minutes, one of the employees would sing loud to demonstrate the power of its acoustics.
