El Escorial

The Royal Site of San Lorenzo de El Escorial (Spanish: Monasterio y Sitio de El Escorial en Madrid), commonly known as El Escorial, is a historical residence of the King of Spain, in the town of San Lorenzo de El Escorial, about 45 kilometres (28 miles) northwest of the capital, Madrid, in Spain. It is one of the Spanish royal sites and functions as a monastery, royal palace, museum, and school. It is situated 2.06 km (1.28 mi) up the valley (4.1 km [2.5 mi] road distance) from the town of El Escorial. 

The Escorial comprises two architectural complexes of great historical and cultural significance: the royal monastery itself and La Granjilla de La Fresneda, a royal hunting lodge and monastic retreat about five kilometres away. These sites have a dual nature; that is to say, during the 16th and 17th centuries, they were places in which the power of the Spanish monarchy and the ecclesiastical predominance of the Roman Catholic religion in Spain found a common architectural manifestation. El Escorial was, at once, a monastery and a Spanish royal palace. Originally a property of the Hieronymite monks, it is now a monastery of the Order of Saint Augustine. 

Philip II of Spain, reacting to the Protestant Reformation sweeping through Europe during the 16th century, devoted much of his lengthy reign (1556–1598) and much of his seemingly inexhaustible supply of New World gold to stemming the Protestant tide. His protracted efforts were, in the long run, partly successful; however, the same counter-reformational impulse had a much more benign expression thirty years earlier in Philip's decision to build the complex at El Escorial. 

Philip engaged the Spanish architect, Juan Bautista de Toledo, to be his collaborator in the design of El Escorial. Juan Bautista had spent the greater part of his career in Rome, where he had worked on the basilica of St. Peter's, and in Naples, where he had served the king's viceroy, whose recommendation brought him to the king's attention. Philip appointed him architect-royal in 1559, and together they designed El Escorial as a monument to Spain's role as a center of the Christian world. 

On 2 November 1984, UNESCO declared The Royal Seat of San Lorenzo of El Escorial a World Heritage Site. It is a popular tourist attraction, often visited by day-trippers from Madrid – more than 500,000 visitors come to El Escorial every year. 

El Escorial is situated at the foot of Mt. Abantos in the Sierra de Guadarrama. This austere location, hardly an obvious choice for the site of a royal palace, was chosen by King Philip II of Spain, and it was he who ordained the building of a grand edifice here to commemorate the 1557 Spanish victory at the Battle of St. Quentin in Picardy against Henry II, king of France. He also intended the complex to serve as a necropolis for the interment of the remains of his parents, Charles I and Isabella of Portugal, himself, and his descendants. In addition, Philip envisioned El Escorial as a center for studies in aid of the Counter-Reformation cause. 

The building's cornerstone was laid on 23 April 1563. The design and construction were overseen by Juan Bautista de Toledo, who did not live to see the completion of the project. With Toledo's death in 1567, direction passed to his apprentice, Juan de Herrera, under whom the building was completed in 1584, in less than 21 years.
