The grand metropolis of Madrid can trace its origins to the times of Arab Emir Mohamed I (852-886), who ordered the construction of a fortress on the left bank of the Manzanares river. Later it became the subject of a dispute between the Christians and Arabs until it was conquered by Alonso VI in the 11th century. At the end of the 17th century, a defensive wall was built for the protection of the new outlying areas, tracing the roads of Segovia, Toledo and Valencia. During the 18th century, under the reign of Carlos III, were designed the great arteries of the city of Madrid, such as the Paseo del Prado and Paseo las Acacias.

At the beginning of the 19th century, Joseph Bonaparte undertook the reform of the Puerta del Sol and vicinity. The commercial street known as the Gran Vía was built as an east-west avenue at the start of the century. In the 1950's the north-south boulevard called Paseo de la Castellana was extended and modern buildings were erected, housing the major financial institutions. Remainings of the distant past are mainly the Baroque and neoclassical strcutures of the 17th and 18th centuries, such as the Plaza Mayor (Main Square), the Palacio Real (Royal Palace) and others which will be described later during our guide of the city.
