Carlos Alberto Square in Porto was named after Albert, King of Piedmont and Sardinia, who was dethroned in 1849. The monarch took refuge in the city of Porto. In the square itself you can see a monument to those killed during the Great War, unveiled on April 9, 1928, by Henrique Moreir. There is also a statue of General Humbert Delgado. At the square, there are, among others, Viscondes de Balsemão Palace, Hospital of the Third Order of the Virgin of Carmo and the famous Luso cafe.
For centuries, this place was called Square of the Blacksmiths, who had their workshops here. The square was at the intersection of important roads, so there was no shortage of inns. Local carpenters manufactured boxes and crates near the square, in which immigrants leaving, for example to Brazil, transported their belongings. That is why this place was sometimes called the Box Market.
