We begin our walk through San Lorenzo de El Escorial at the Bus Station. Our tour takes us to the street Juan de Leyva, which is a pedestrian section in which we can observe an 18th century building, the Casa para arrendar (Rental House) of the Marquis of Campo Villar (1), carried out by the architect Juan de Villanueva. Farther on, to the left, we find one of the façades of the Family House of the Secretary, later called the House of the Count of Ricla (2),a noble title since the year 1772, it can be recognised by its current pink colour, the building covers the entire block.

We reach the street Duque de Medinaceli having to cross the street del Rey and it ends in the Plaza de San Lorenzo, again a pedestrian section. Making a corner and to our right we can observe the house of Felipe Díaz Bamonte (3) and following its façade to the left, the Plaza turns into the street Reina Victoria in which is located the Casa de la Tiendas o las Columnas (4) (House of the Stores or the Columns) that originally provided shelter for travelling sellers, who in times of the Visits passed the night outdoors.

We reach the intersection with the street de las Pozas, to our right, in which is located the Cuartel de Inválidos y Voluntarios a Caballo (5) (the Barracks of the Disabled and Volunteers on Horseback), dated in 1774; there are doubts about its authorship. At present the Centro de Estudios Herrerianos (Centre for Herrerian Studies) is found inside, which will soon be open to visit.

Returning over our steps, we will see the Plaza de la Constitución (Constitution Plaza) which we will have to go around; leaving the City Hall to the right, we see in front of us one of the façades of the Tercera Casa de Oficios (6) (Third House of Trades), also called the house of the First Secretary of State, declared Site of Cultural Interest.

Once in the Street Floridablanca and following the street downhill, we observe on our right the Segunda Casa de Oficios (7) (Second House of Trades), constructed in the 16th century, which we will explain later together with the First. We reach the Plaza Jacinto Benevente, to our left, where the Casa de los Doctores y Catedráticos del Colegio (8) (House of Doctors and Professors) is found; designed by Juan de Herrera in 1583, it housed lay professors who taught classes in the Escorial school.

In 1587 Herrera designed a thick wall under these houses: the wall of the house of the doctors, to contain the land and resolve the slope to the current street of Floridablanca. At this point we see on our right the Primera Casa de Oficios (9 ) (First House of Trades) that together with the Second, mentioned previously, occupied land that in principle had held an enormous camp of dwellings for workers. They are declared Sites of Cultural Interest. Currently the First House is the Cultural Centre that houses different exhibition halls.

Continuing forward on the street Floridablanca and returning to the 18th century, on our left is the Real Coliseo Carlos III (10) (Carlos III Royal Coliseum), designed and constructed by the architect Jaime Marquet in 1770 for the enjoyment of the Court during the Royal Visits. Its reconstruction was awarded among others with the National Restoration Prize 1980 by the General Department of Fine Arts of the Culture Ministry and has been declared Site of Cultural Interest.

A little farther on, on our left, is the Fonda de los Milaneses (11), (Boarding House of the Milanese), also of the 18th century; its function: the renting of rooms during the Visits. On the same sidewalk and almost ending the street we find the Reales Cuarteles de Infantería de Guardias Españolas y Valonas (12), (Royal Barracks of the Spanish Guard Infantry and Walloons), work of Juan Esteban in the 18th century.

At the end of the street, we turn to the right, go down a small section of the Plaza Virgen de Gracia and we face one of the façades of the Monastery (13), the end of our tour and inimitable work of the 16th century.
