The marble used for the arch is of a lower grade that had more inclusions than that used in the best Athenian buildings. The arch was constructed without cement or mortar from solid marble, using clamps to connect the cut stones. It is 18m high, 13.5m wide, and 2.3m in depth. Its design is fully symmetrical from front to back and side to side.
