Andron A. It was built by Idrieus (351-344) and had a front of 12 m. of width and 10,5 of height in marble, with two Ionic columns and a Doric frieze with triglyphs. A notice at the site indicates it must have had couches along the walls and probably in a niche in the back wall statues of Mausollos and his wife Ada as well as Zeus, the god.
One of some details I took during an earlier visit.
