local poros stone was used for the foundation and limestone for the parodoi (passageways), which sloped to the orchestra in order to diminish the difference in height with the cavea. the theatre seated 6,300 spectators and is reminiscent in form to the theatre of dionysos in athens, after transformation of the latter in 330 bc. following the destruction of eretria by the romans in 198 bc, it was rebuilt with lower quality materials and the rooms to the south of the "parodos" were then apparently decorated with colour mortars of the first pompeian style.
