The excavational research of the last decade at Myrina, Lemnos, has brought into light new, abundant data concerning the ancient topography of the city and the history of the island. The remnants of a large littoral settlement at the site Richa Nera, which seems to resemble Poliochni, are proven to be of special importance for the inhabitation of Lemnos during the Early Bronze Age. As regards the historic times, the location of sanctuaries in and outside of Myrina, ceramic and koroplastic workshops, fortifications, cemeteries etc., certifies on the one hand the importance of the city -equal to that of Hephaestia- from the eighth century B.C. to the Roman period, included, and on the other its considerable extension.
