Medusa Heads at Basilica Cistern

Where are the Medusa Heads?
The two Medusa Heads are located in the northwest corner of Basilica Cistern. They support columns at the base level, so look down near the water rather than up at the ceiling or arches.
Why are they sideways and upside down?
No single explanation is certain. The most accepted view is that the Medusa blocks were reused from an earlier Roman building and placed in the cistern as practical column bases. Their sideways and upside-down positions may have been chosen for structural reasons, symbolic reasons or simply because the blocks were reused material.
Why is Medusa important?
In Greek mythology, Medusa was a powerful figure whose gaze could turn people to stone. This mythological background makes the two heads feel even more mysterious inside the dark, water-filled underground space.
