It's from ancient Eygpt -- 1490 BC. The other is the Serpent Column. It once was 8 meters tall, with 3 serpent heads supporting a golden bowl and was created to commemorate the Battle of Plataea in 479 BC. One of the serpent heads is displayed in the istanbul Archaeology Musuem, but this is all that remains at the Hippodrome:

Next to the Hippodrome is the Blue Mosque, built in the early 1600s and so named for the blue tiles in the interior.






Next to the mosque (on the same grounds) is the tomb of Ahmed I.

Underneath Sultanahmet is the Basilica Cistern, dating to the 6th century. It's huge with columns everywhere. And a nice escape from the heat. At the back, there are two Medusa heads used a column bases and clearly taken from some other location and brought there for unknown reasons.
