Omonia metro station

Omonia (Ομόνοια, ) is an underground station under the Omonoia square of Athens, used by Athens Metro Lines 1 and 2.

The first station opened 1895, but was relocated underground and redesigned by the Hellenic Electric Railways (which operated Line 1 at the time) in 1930. In January 2000 the additional platforms for Line 2 were opened.
