These caves were discovered back in 1947 in the region of Mira de Aire, Portugal. The entrance is 300m high and inside it reaches 180m. The magnificent shapes of stalagmites and stalactites are illuminated with colored lights and Classical music follows you in the background. Apparently its formation takes back as much as 150 million years. It is believed that the cave already existed during the Jurassic time when the dinosaurs populated this region. There are also traces in the ground which can be found at the Natural Monument of the Dinosaur Footprints located in Estrada de Fatima, Serra de Aire in Ourem. #travelphotography #travelblogger #blogger
