What I can see

In front of the Stoa of Attalos, there was the Monopteros, a circular building with a diameter of 8.14m. Today, we see part of the toothed and ornate architrave.

What I can't see

Part of its foundation was made of tufa stones. It had 10 marble columns of green and white colour, an elaborate architrave of Pentelic marble, and a brick dome, with the bricks arranged horizontally, a rare technique for the time. The name Monopteros comes from the descriptions of Vitruvius, but the building may not have been a temple after all, but a fountain.
