Of Andron B not much remains. It was built by Mausollos (377-352 BC), it had a 10,5 metres high and 12 metres wide marble front. It had two ionic columns and a Doric frieze. Inside there were couches along the walls for the sacred meal. In the niche in the back wall there were possibly statues of Mausollos, his wife Artemisia and the god Zeus.
This picture shows what remains of the columns in the front, and the contours of the room in their back.
