Valle de Cuelgamuros is home to the Basilica of the Holy Cross of the Valley of the Fallen, located in the Sierra de Guadarrama, Spain. Completed in 1959, this underground basilica features a 150-meter-high cross and a 262-meter-long nave, making it one of the largest in the world.

The basilica, built under Francisco Franco's regime, serves as a burial site for those who died during the Spanish Civil War. It is carved into a granite ridge in the Guadarrama Mountains. Visitors can access the site via the A-6 highway from Madrid, approximately 50 kilometers away, or by train to nearby towns, followed by local transportation.
