[1] It hosts Triumphal Arch of the Lorraine and, in winter, an ice rink for skating.
In 1738, the square's Triumphal Arch of the Lorraine was erected to celebrate the arrival of the Habsburg-Lorraine dynasty in Florence.
In 1865, the demolition of the medieval walls allowed for a new reshaping of the area by the architect Giuseppe Poggi, completed in 1875 in the present elliptical shape square, surrounded by palaces.
[2] In the middle of the tree-lined park is a pool with fountains in front of the triumphal arch.
There was a French garden in the 18th century that was wanted by Granduca Pietro Leopoldo, when Giuseppe Poggi created the square (when Florence was the capital of Kingdom of Italy), but he decided not to modify it.
