Monuments of Aphrodisias
This monumental gate, located on the main north-south avenue which runs past the Sebasteion and Agora Gate, was first constructed in the 2nd century CE. It is so named because it is constructed of four groups of four columns, topped with elaborate and exquisitely carved architectural and sculptural ornament.
The Tetrapylon stands as it does today because of a massive restoration effort, or anastylosis. More than 80% of the original marble blocks survive, and detailed excavation and recording of those blocks allowed experts to figure out the original position of each stone, and reconstruct the monument using the original stones in their exact locations.
