On this day, we suggest you explore two different locations outside the capital. You should start by the historical town of Ávila, recognized for having the best-preserved medieval walls in the world. Spend some time wandering around and admiring this stunning feat of human ingenuity, but don't forget to visit the Cathedral and the San Vicente Basilica.
On the way back to Madrid, you should stop for a visit to the highlight of the day: the Monastery of Escorial. Being one of the greatest symbols of the Spanish Golden Age, this impressive monastery was the first example of the Herrerian architectural style and it is composed of 15 cloisters, 13 oratories, 86 staircases, 88 fountains, more than 1,600 paintings, nine towers, and 73 sculptures.
