The Cathedral of the Notre Dame of Flowers, the Vicio Palace in Florence, is still fulfilling its original mission as a city hall. It was completed in 1322, when a large bell was placed in a bell tower next to the palace to call for public gatherings and warnings of fire, floods or enemy attacks. Just arrived in Florence, we opened the door of the Renaissance through interesting prohibition signs. Ancient Florence attracted artists everywhere. More than 700 years ago, there was no pillar or concrete on the roof, but it became a miracle in the world's architectural history. It was fixed with two-story roof and fishbone structure, and so far there are no architectural drawings. Walking into the Vickio Palace is even more shocking! ___________ Stairs and armrests are made of a unique stone, and Michelangelo's statue of David on the left side of the main entrance of the palace is called the most perfect golden ratio figure!
