From Madrid: El Escorial and Valley's Basilica Half Day Tour

On this 5-hour tour from Madrid, you'll begin with a visit to the Monastery of El Escorial. It was built under the reign of powerful King Philip II as a residence for Spanish kings, a monastery, and a royal pantheon.
It became a symbol of the great power of the Spanish Empire at that time. The monument was declared to be of artistic and historic importance and a UNESCO World Heritage Site.
The Valley of the Fallen was built in 1936, about 9 kilometers from Escorial, as a memorial to those who died during the Spanish Civil War. 
Situated in a beautiful valley in the Guadarrama Mountains, this impressive work features a cross standing more than 150 meters high, as well as a basilica and crypt built into the hard rock under the mountain.
The tour includes admission to the Valley as well as a visit to the basilica's interior.
