Zona Arqueológica de Las Médulas #2

Las Médulas is a historical site near the town of Ponferrada in the region of El Bierzo (province of León, Castile and León, Spain), which used to be the most important gold mine in the Roman Empire. Las Médulas Cultural Landscape is listed by the UNESCO as one of the World Heritage Sites.

The spectacular landscape of Las Médulas resulted from the Ruina Montium, a Roman mining technique described by Pliny the Elder in 77 AD. The technique employed was a type of hydraulic mining which involved undermining a mountain with large quantities of water. The water was supplied by interbasin transfer. At least seven long aqueducts tapped the streams of the La Cabrera district (where the rainfall in the mountains is relatively high) at a range of altitudes. The same aqueducts were used to wash the extensive gold deposits.

The area Hispania Tarraconensis had been invaded in 25 BC by the emperor Augustus. Prior to the Roman conquest the indigenous inhabitants obtained gold from alluvial deposits. Large-scale production did not begin until the second half of the 1st century AD.

Spain (ⁱ/ˈspeɪn/ spayn; Spanish: España, pronounced: [esˈpaɲa] ( listen)), officially the Kingdom of Spain (Spanish: Reino de España), is a country and member state of the European Union located in southwestern Europe on the Iberian Peninsula. Its mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with the British Overseas Territory of Gibraltar; to the north by France, Andorra, and the Bay of Biscay; and to the northwest and west by the Atlantic Ocean and Portugal.

This is a specific list of the UNESCO World Heritage Sites in Europe. Israel and the Caucasian and Siberian parts of Russia are included both in this list and in the list of sites in Asia. Overseas sites of France, the Netherlands and UK are included here, but are also repeated in the geographically relevant lists. Kazakhstan, despite having a small portion lying in Europe is to be found under Asia, where both its world heritage sites are listed.

Sites marked with an asterisk (*) are also included on the List of World Heritage in Danger.

Europe (pronunciation: /ˈjʊərəp/ yewr-əp or /ˈjɜrəp/ yur-əp) is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally 'divided' from Asia to its east by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways connecting the Black and Aegean Seas. Europe is bordered by the Arctic Ocean and other bodies of water to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and the Black Sea and connected waterways to the southeast. Yet the borders of Europe—a concept dating back to classical antiquity—are somewhat arbitrary, as the primarily physiographic term "continent" can incorporate cultural and political elements.
