The Salamanca district is one of the most significant areas of Madrid, both for its peculiar layout and for the residents who have traditionally inhabited its emblematic streets. Its construction dates back to the second half of the 19th century and corresponds to the urban expansion carried out during the reign of Isabel II. The precursor to whom it owes its name was José de Salamanca y Mayol, the Marquess of Salamanca from Málaga, who conceived a new location with carefully planned buildings to house the aristocratic and bourgeois classes of Madrid. Of 19th-century style, it is characterized by its special regular checkerboard distribution with perpendicular streets. Its buildings are of particular interest due to their architectural quality and the beauty of their facades. Traditionally, Salamanca was a residential area, especially inhabited by the country's political and economic elites. In the last fifty years, this residential character coexists with other activities such as business, diplomacy, and especially commerce, as it is one of the most important luxury fashion areas in the capital. In this district of Madrid, and as a true jewel of it and the green lung of the capital, we find the Parque del Buen Retiro.
