Sürmene (Greek: Σούρμενα, Sourmena) is a town and a district of Trabzon Province in the Black Sea region of Turkey. In ancient times it was also know as Hyssus or Hyssos and Issiporto.[1]
The little town of Sürmene (Hamurgan) is situated some 40 km (25 mi) east of Trabzon. Known in antiquity as Susarmia or Augustopolis, it lies on the River Kora (Manahoz Deresi) and is best known as the place where Xenophon and his Ten Thousand fell sick after eating wild honey, an event which was confirmed by the local people. In the village of Sürmene Kastil, 5 km (3.1 mi) to the west of Sürmene, stands a ruined medieval castle as well as the impressive 18th century Yapukoğlu Konağı mansion (Derebeyli Kale). It was formerly the seat of the Yapukoğlu family, who lived here as rulers (derebey) of the surrounding region relatively free of interference from the Sublime Porte in Istanbul.
