Corral de Comedias

Founded in 1499 by Cardinal Cisneros, and the centre of academic excellence in Spain in the 16th and 17th centuries. Visit by guided tour only, hourly in Spanish, in English at 14:00. The tour takes in the ornate plateresque façade, the three interior patios, the mudejar chapel, and the Paraninfo auditorium where the Cervantes Literary Prize is presented by the King annually on April 23. The university goes back to an older institution that did not teach the full range of subjects of a "proper" university founded in the 13th century and was moved to Madrid as the modern day Complutense University in the 19th century. In the 20th century a new university was founded in Alcalá.

A 15th-century charity hospital, probably the oldest in Europe in continuous use. Nowadays it's a care home for the elderly.

This is the house where the famous author of El Ingenioso Hidalgo don Quijote de la Mancha was born in 1547, and lived his early days. The museum recreates life in a Spanish house of that period, though perhaps a more stable, prosperous household than Cervantes' own. His father was a barber-surgeon, so the old shaving & blood-letting bowl foretells Don Quixote's mad helmet. The book was widely translated soon after Part One was published in 1605, and there's an impressive collection of translations and other books and manuscripts from around the world. Free admission but to avoid overcrowding they only let in a dozen or so at a time, so there may be a queue.

The museum is housed in the 17th-century Madre de Dios monastery-college on Plaza de las Bernadas. Prehistoric and Roman finds from the area.

The palace built as a fortress in the 14-15th century, turned into an episcopal palace in the 16th century, but much of it burnt down in 1939 during the Civil War. England's Katherine of Aragón and Germany's Emperor Ferdinand were born here, John I of Castille died here, and the first meeting (the Spanish term "entrevista" literally means "interview") where Christopher Columbus pitched his idea to Queen Isabel of sailing west to reach India took place here. You can't visit the interior.

It was built in the 15th century, but rebuilt after fire damage in 1939. It's called a "magisterial" cathedral because its clerics were all masters, ie graduate teachers of the university. Contains the Cripta de los Santos Niños a reliquary dedicated to two children who were supposedly executed for their Christian faith under emperor Diocletian allegedly also containing their mortal remains. It's also Cardinal Cisneros' site of burial although his much more elaborate tomb is found in the Chapel of San Ildefonso on University grounds.
