The octagonal Battistero di San Giovanni (Baptistery of St. John) is one of the oldest buildings in Florence. It is located opposite the Duomo Cathedral (full name Santa Maria del Fiore) and Giotto's bell tower. This fascinating structure, combining faith, history and art, delights us with its harmony in accordance with the Duomo and Giotto's tower. It was built between the 11th and 12th centuries, and it was there until the end of the 19th century that all Florentine Catholics were baptized, like Dante Alighieri, and many famous Renaissance figures, including members of the Medici family. According to the style of construction it belongs to Florentine Romanesque architecture. Of her beauties, we would single out three front doors that show a biblical theme - the south door was made by Andrea Pisano, north and east by Lorenzo Ghiberti. For the east door Michelangelo used the term "Gate of Paradise". There is a copy today, while the original is kept in the Museo dell'Opera del Duomo. The gates of Paradise consist of 10 fields, depicting the expulsion of Adam and Eve from the Garden of Eden, as Moses receives the 10 Commandments of God, until the fall of the city of Jericho and the battle with the Philistines. The interior of the Baptistery is richly decorated, the ceiling is decorated with a beautiful mosaic of gold, one part of which depicts the Last Judgment, which had a great influence on Dante when writing his Divine Comedy.
