The Coin Caves (Grutas da Moeda) are located in São Mamede, municipality of Batalha, only 2 Km away from Fátima. Its discovery happened in 1971, as two huntsmen that were chasing a fox, saw it enter by one natural hole under the bushes. Moved by curiosity, they decided to enter in the galleries filled of beautiful limestone formations. Then they realised about Its natural beauty.
For some months, the two men kept exploring, reaching the galleries wich revealed to be very interesting, scientific and touristically. These same galleries, are actually the visitable part of fhe Caves. Later, a group ofin the geologists and speleologists confirmed the Caves´ scientific importance. Along the years, the main concern was and still is to preserve riguroslly, not only the Caves, but also Its surroundings.
The Caves´ visitable extension is 350 meters length and 45 meters depth below the entrance point. Temperature is constant around 18ºc all year long.
