Kalindria

The village is located 18 km north of Kilkis on the road to Doiran Lake and Rodopoli, Serres.

[a] The highest point in the vicinity is 537 metres above sea level, 6.6 km northeast of Kalindria.

[1] According to a hypothesis of Yordan Ivanov, near Krondirtsi was the fortress Kolidron (Kolidros, Kolindron), defended by Samuil's voivode Dimitar Tihon and conquered in 1002 by the Byzantine emperor Basil II.

[8] In the Ethnography of the Provinces of Adrianople, Monastir and Thessaloniki, published in Constantinople in 1878 and reflecting the statistics of the male population from 1873, Crondirtzi is mentioned as a village with 80 houses and 389 Bulgarian inhabitants within the Demirhisar Kaza of the Sanjak of Serres in the Ottoman Empire.

The Kilindir Sector of the Macedonian front was the scene of fighting between the Bulgarians and the Entente forces dominated by the Armée d'Orient (1915–1919).

[16] Every year, on January 8, the inhabitants revive the custom of "Babos" (Feminism) according to which the women of the village impose their absolute power for one day with the central figure being "mammi" or grandmother.
