Myrina Castle
One of the largest castles in the Aegean crowns the steep volcanic peninsula that divides Myrina's two bays, its highest point 114 m above the sea. Byzantines built a fort on the ancient acropolis in the 12th century, and Venetians, Byzantines and Ottomans reshaped it over the centuries; its outer wall runs for about 1,200 m with 14 towers, and the main gate on the east side opens through three successive doorways. The walls give wide views over both bays. The walk up from town takes about 20 minutes.
Archaeological Museum of Myrina
On the Romeikos Gialos seafront, the island's archaeological museum fills a 19th-century two-storey building that once housed the Ottoman governor's office. Its permanent exhibition shows finds from Poliochni, Myrina, Koukonisi, Kavirio and other sites: the prehistoric civilisation of Lemnos on the first floor, and historic times from the Late Bronze Age to the Byzantine era, with a fine collection of sculptures, on the second. Tickets EUR 10, reduced EUR 5.
Poliochni
On a low rise above the bay of Vroskopos on the east coast stands Poliochni, one of the great early urban centres of the Early Bronze Age and considered the first city in Europe with a basic social and civic structure. First settled in the Neolithic, it grew to almost 1,500 people, with strong walls, public buildings, squares, paved streets with drains, wells and stone houses, until an earthquake ended it. Tickets EUR 5, reduced EUR 2.50.
Sand Dunes of Limnos
On the north side of the island, near the village of Katalakkos, the sand dunes known as Pachies Ammoudies form a small desert landscape that is rare in Greece, shaped by the constant play of wind and sea. Sparse sea lilies, chaste trees, thyme and oleanders grow on the sand, with olive and wild pear trees around it, and the light is best early in the morning or late in the afternoon. Gomati Beach, with fine sand and clear water, is about 4 km from Katalakkos. Entry is free.
