Comunidad de Madrid

The Comunidad de Madrid (Community of Madrid) is obviously named after the city Madrid, which is the capital and most populous city of Spain. It is located in the centre of the Iberian Peninsula on the Meseta Central (Central Plateau) between 600 and 1,000 m asl. Neither the plain, nor the surrounding mountain ranges, have show caves or show mines. But the capital has numerous artificial underground sites, mostly underground museums. Several subway stations, abandoned and still operational, are used as museums.
