Apparently it was a rectangular building, bearing a clerestory along its western side, and perhaps with a tripartite interior arrangement.
Its renown is due to its hosting two famous paintings of the Thasian painter Polygnotus, namely the Capture of Troy (Iliou Persis) and the Nekyia (the visit of Odysseus to Hades).
that inside the lesche there were two rows of four wooden columns, placed symmetrically to support a clerestory.
Due to the large fragmentation of the monument, scholars are not in a position to give definitive answers regarding the entrance, the windows, the roof, and the arrangement of the paintings by Polygnotos inside the Lesche.
[2][3][4] In the course of the 4th century BC, to the south of the monument was built a wall made of local limestone, on which may have been exhibited votive offerings, according to the model of the Athenian Treasury.
