The Plaza Mayor de Salamanca is an urban space built as a main square that over time has become the center of social life in the Spanish city of Salamanca.

It was built in the period from 1729 to 1756, in the Baroque style. The design is by the architect Alberto Churriguera (Real and San Martín pavilions) and later continued by others with few modifications with respect to the initial project.

At the beginning of the 19th century it underwent various urban remodeling, until little by little in the middle of the 20th century it was deprived of its gardens, central bandstand and public urinals to make it diaphanous.

Miguel de Unamuno defined the square, which is considered an Asset of Cultural Interest, as follows: “It is a quadrilateral. Irregular, but amazingly harmonious.

The original square was born naturally in a field where it was traded, next to the old Puerta del Sol of the Salamanca wall and, since the church of San Martín was located there, it was known since the 15th century as San Martín Square.

This square was much larger than the current Plaza Mayor, almost four times more, being considered "The largest square in Christendom", in which all the functions of a square were performed simultaneously (festivals, market, etc.) .
