The Cathedral of Santa Maria del Fiore is truly magnificent. Admission is free, allowing you to experience the grandeur of its interior without having to pay. Tickets can be purchased through the side entrance, bypassing the main entrance line, and include access to the bell tower. However, if you're looking for a panoramic view of Florence from above, you can choose between the dome or Giotto's bell tower, or both. The dome offers a close-up view of the frescoes and panoramic views of the city. The bell tower also offers a fantastic view, allowing you to capture the dome in full photographic space. Both steps are quite demanding, as they are quite long and challenging.
