Subways in Madrid

A neighborhood represented by an apparent geocentric and flat-earth model of the Solar System is hidden in the subway of Madrid.

A small museum displays some of the artifacts discovered during a subway station renovation.

Replicas of fossils unearthed during renovation work reveal how this area would have looked millions of years ago.

This small museum tucked within a subway station holds pieces from Madrid's past.

Abandoned for decades, trains still pass through the now-restored remains of one of Madrid's first metro stations.
