Valle de Los Caidos, or the Valley of the Fallen, is a unique and historic monument located in the Sierra de Guadarrama mountain range in Spain.
It was built between 1940 and 1958 as a tribute to the victims of the Spanish Civil War and is considered one of the most controversial monuments in Spain's history. The main attraction of the valley is the Basilica of the Holy Cross, which is carved into the rock face and is one of the largest churches in the world. The basilica is home to the tombs of General Francisco Franco and José Antonio Primo de Rivera, the founder of the Falange party.
Visitors to the valley can also explore the extensive underground tunnels, which were used as a prison during the Franco dictatorship. The tunnels offer a glimpse into the history of the Spanish Civil War and the dictatorship that followed. The valley also has beautiful gardens and a museum that displays artifacts and documents related to the Spanish Civil War.
Despite its controversial past, the Valle de Los Caidos is a must-see attraction for those interested in Spanish history and architecture. The valley offers a unique and haunting glimpse into one of the most tumultuous periods in Spain's history and is a powerful reminder of the sacrifices made during the Spanish Civil War.
