One of the main reasons why the Uffizi Gallery is so famous is that it houses some of the greatest masterpieces of artwork of all time. From the work of Botticelli and Michelangelo, the Uffizi Gallery is one of the oldest and most important galleries in the world.
It was first established in 1581 but didn't officially open to the public until 1765; it also later became a museum in 1865 and is now one of the most popular tourist attractions in Florence.
The Uffizi Gallery is also one of the most visited art museums in the whole world, and millions (more than 2.2 million!) of tourists flock to it each and every year to admire the work of the world's most famous and beloved artists. In 2016, it was the most visited art gallery in the whole of Italy, so it's not hard to see why it's so famous all around the world.
