Callao Square is located in the Sol neighbourhood, in the centre of Madrid, at the end of Carmen Street. It offers access to the third section of the Gran Vía until it ends at Spain Square, and it was an integral part of the ambitious urban reorganization plan at the beginning of the 20th century.
Built from 1917 until 1927, Callao Square was originally a small square located on Preciados Street. When work began in 1917, the square acquired great importance because it provided access to Puerta del Sol. However, the Gran Vía completely removed its prominence.
After the end of the Spanish Civil War in 1939, small businesses began to emerge around the square. This led to a new urban reform to expand its size. In 2010, vehicle access was completely eliminated, and the square was pedestrianized with the intention of serving as an important tourist epicentre.
In addition to being a natural meeting point thanks to its large number of venues, bars and restaurants, Callao Square is surrounded by splendid buildings and heritage monuments. Among them are the Carrión Building, the Palace of the Press and the Callao Cinema Building.
The other reason it is such a popular square is that a series of direct means of transportation converges around it, such as the Madrid Metro and a bus line. In addition, it crosses many important communication routes. This translates into pedestrian traffic of more than 100 million people every year.
