The remains of the town of Abai are located on a very rocky hill southwest of present-day Exarchos. In particular, some remains of the walls have been preserved, on the south side, there are remains of 2 walls, one higher up the hill and the other lower. Accessibility is very limited, but from the top there is a view over the entire valley, with Hyampolis hill in the distance. In ancient times there was an important oracle of Apollo in Abai, which was destroyed by the Persians, but was worshiped until the Roman period. No traces of this oracle remain. I did not visit the temples and graves on the map.
