When viewing the rock formations of Las Medulas, it's important to remember that this landscape is not natural, but rather the (sad) remains of a mountain range that was ruthlessly exploited for its gold ore as early as the Roman Empire. Nevertheless, this landscape of ruins is a UNESCO World Heritage Site. A 15-minute film documentary about it (although only available in German) is available in the ARD media library as part of the highly recommended series "Treasures of the World - Heritage of Humanity" =>> https://www.zdf.de/swr/schaetze-der-welt/page-video-ard-las-mdulas-und-seine-goldminen-spanien-100.html

Las Médulas, located in Bierzo, northwest of the Montes Aquilanos and along the valley of the Sil River, is a fantastic landscape resulting from Roman gold mining. This place has been declared a World Heritage Site by UNESCO. Although no one would say that the steep cliffs hide, beneath their bowels, the gold of the Romans, the mining exploitation silenced for centuries has become a beautiful landscape of great tourist attraction.

La Cuevona and La Encantada are two impressive places in Las Médulas, an area with a rich mining history and a unique landscape. The Cave: It is a gallery dug into the mountain, part of the ancient network of tunnels and galleries used in Roman mining exploitation. It has the highest height of all the existing galleries in Las Médulas. It is an important reference point for those exploring the Las Valiñas path. As you pass in front of La Cuevona, you will climb a small slope protected by a railing of wooden logs. The enchanted: It is also part of the old mining network. Upon arriving at La Encantada, you will be surprised by its unusual luminosity due to the entry of light from a hole at the top. There are two tunnels that branch off to the left and right, and from inside, you can see a beautiful landscape. Both caves are witnesses of Roman mining activity and offer a unique experience for visitors. I hope you enjoy exploring La Cuevona and La Encantada! 🏞️🚶♂️

Pico de Placias is another impressive place for hiking and nature lovers. A popular route starts from the parking lot next to the archaeological classroom. The route is circular, following the perimeter path to the Orellán viewpoint and then linking with the Valiñas path in the direction of La Cuevona and La Encantada. I hope you have an amazing experience exploring Placias Peak! 🏞️🚶♂️

The Orellán Gallery is an ancient underground water conduit that extends for about 100 meters. Its original function was to transport water from inside the mountain to burst it from within. The conduit ends at a viewpoint located in a vertical cut of the mountain, offering an impressive view. These galleries were part of the mining exploitation system known as Ruinae Montium. The Romans used these structures to extract minerals and natural resources. I hope you enjoy this historical and natural experience! 😊
