added by archaeologs To the left of the Oikoi Building, to the south, stands the second banqueting hall (the so-called Andron A), presumably built by Idrieus (351-344 BC). This is the most well-preserved building at the site, with its southern wall standing to a height of 7.9 meters above the level of the foundation of the pronaos floor. In plan it is almost identical to Andron B but it is slightly larger, being 12.26 meters wide and 22.13 meters long, including the niche. Its original height was ca. 10 meters to the apex of the pediment at the front. One distinctive difference from Andron B lies in the enormous thickness of the entrance wall, which is 1.85 meters. Possibly this wall construction was intended to safeguard the building against earthquake damages. In ancient times the surrounding topography of the building was different. On the southern side there was no terrace. Here the andron was resting on a podium of coarsely worked ashlars, of which only the uppermost course can be seen today. The front of the building, entirely of marble, had the same unusual combination of Ionic columns and a Doric entablature as Andron B. Above the present gneiss walls the architrave, triglyph frieze (with four metopes to the span) and geison encircled the building on all sides. The roof was covered with tiles, probably also of marble. The inscription on the architrave, of which only three short sections are preserved (marked in black), shows that this building was also called andron.
