Geography

In the Ottoman Empire
In 1891 Georgi Strezov wrote: "Palmesh, several neighbourhoods on the west of Poroy [modern name of Ano Poroia], 6 hours drive at the foot of Belasitsa and Pear mountain. Approximately 200 houses, all Pomaks. They speak Bulgarian with a slight difference from Poroy; they dress in a special red garment-anther and poturi. They come to the market in Poroy with fish from Doiran Lake."

According to the statistics of Vasil Kanchov ("Macedonia. Ethnography and Statistics") by 1900 "Palmesh" ("Palmesha") is a Bulgarian Muslims' settlement. 1150 Bulgarian Muslims were living there at the time.

Under Greek sovereignty
During the First Balkan War the village was under Bulgarian control, but after the Second Balkan War in 1913 it was incorporated within Greece.
