The Athens Metro/Subway system
is like an open museum.
During the building of the lines and stations,
many ancient artifacts were discovered.
These artifacts are now displayed
and decorate the stations.
As you walk, you may walk over a glass walkway
revealing an ancient roadway or the side of a building,
vases, children's toys and an array of other things.
Athens has been rebuilt over and over and
one travels through the centuries when they are here.
