Because it is the first village that anyone entering the Gulf of Moudros sees, the name is said to have come from the lamps that sailors saw as they sailed into the bay at night.

The parish church of Agios Dimitrios was constructed in 1865. The temple was renovated in 1905, thanks to the efforts of immigrants from the United States, who collected $456. Finally, in 1924, a stunning outdoor narthex of a single carved stone was added to the building. Two carved columns with intricate caps visible on the church are most likely from a previous temple. In 1910, a prominent site was chosen for the school building. In the town, there is a restored windmill that towers above a local hill at the edge of the village.

Lychna produced several well-known prestigious figures. There was Nikolaos Dallis (1855-1933), a famous benefactor of Lemnos who grew wealthy in Egypt and was the driving force and president of the Lemnos Brotherhood of Alexandria until 1910, when he went bankrupt. He gave 1.5 acres to the Lychna school to be used as a school garden. There was also Charalambos Karapanagiotis (1912-2006), a teacher who worked in Thrace, Varos, Moudros, and Athens. He was an acquaintance of resistance port leader and witness Ioannis Arvanitakis during the occupation. Panagiotis Kontaridis (1873-?) is a Smyrna graduate who became a priest and teacher.  He served in Plaka (1903-04) and Tsimandria (1903-04)(1905-10).
