These are the remains of the east side of the 1st - 2nd Century AD Agora of Hieropolis. Huge 20-meter (65 foot) tall columns such as the one left standing formed a complete portico running the 280-meter (300 yard) length of the Agora. (There are photos of some of the capitals of the columns earlier in my photostream.) The marble steps led up from the floor of the 280 by 170 meter Agora to the covered portico.
The Agora was a combination primary commercial space; the porticos surrounding it on all four sides were full of shops and the main center area was used as a trading center. It was also a sacred space for public worship and a place for holding gladiator games and other entertainments.
The house lies along the secondary road that leads to the theatre. The original structure dates the the second century AD. The domus, which must have belonged to one of the aristocratic families of the city, is organized in various rooms that open into a central square peristyle, with three columns per side surmounted by Iconic capitals that have given the name to the house.
During the fourth century AD the house was radically restructured, with creation of a reception hall, with an opus sectile pavement, and the definitor of a new living area in the eastern part of the insula. An important discovery is an inscription painted on the wall of an early Byzantine house, with the prayer of Manassas, a biblical apocryphal text. The earthquake of the first half of the seventh century destroyed the houses."
