Its exterior is paved with marble blocks of different shades of white, green and pink. The colors are colorful and harmonious △ In 1982, the cathedral was listed as a World Cultural Heritage as part of the historical center of Florence. After entering the church, you can climb up to the dome from the small door on the side. You need to climb 463 steps, and then overlook the entire city of Florence. △ The bell tower of the church is a Gothic building, 85 meters high. It consists of a six-story square structure stacked upward into a column. The outer wall is paved with white marble, which is pure and elegant, bringing more momentum to the majestic church.Italy · Florence

Piazza del Duomo

4.6/5

Piazza del Duomo is located in the heart of the historic center of Florence, which was inscribed on the UNESCO World Heritage List in 1982. The square has been the city's religious center since the Middle Ages. In the late 13th century, surrounding residential buildings were demolished to build the new cathedral and bell tower, and it was gradually expanded over the following centuries to its current size. The square brings together three iconic buildings: theCathedral of Santa Maria del Fiore, Giotto's Bell Tower, and The Baptistery of San Giovanni. Together, they form the "Cathedral of Santa Maria del Fiore complex," showcasing the evolution of architectural art in Florence from the Middle Ages to the Renaissance. The dome designed by Brunelleschi stands over 90 m high and is a striking visual focal point on the square's skyline. Historic buildings such as the Archbishop's Palace, the Cathedral Museum, and the Bigallo Museum are also located around the square. Standing in the center of the square and looking around, the facades of buildings from different eras and styles complement each other, making it a key location for experiencing the urban landscape of Florence.Italy · Florence

It was windy and rainy on the day we went to Terce Castle. It was really cold on the mountain. The castle was rather run-down and there were not many tourists. You can see the whole city from the mountain. If it is not on your way, I would not recommend it. After a round trip, we set off for Zadar.

The queue was quite long, and you need to make sure you're in the correct line before you start queuing… Queues at tourist attractions in Europe often consist of several separate lines with unclear signage. I didn't choose to climb the bell tower or the dome, but the museum included in the ticket is worth a good look; personally, I felt the environment was quite nice.

such a lovely place, the duomo or cathedral is very big that I cannot take a picture of the whole cathedral. Even if I have seen it several times I always love to visit and see it again and again.
