Ormenio
Ormenio stands near the Maritsa, known in Greek as the Evros, in the lowlands of Thrace. Called Chernomen in Bulgarian and Çirmen under Ottoman rule, it had a fortified position by the river. In 1371 an Ottoman force surprised the army of the Serbian rulers Vukašin and Uglješa near Chernomen. Both brothers died in the defeat, which opened the way for further Ottoman advances into Macedonia. By the mid-fifteenth century Çirmen had also given its name to an Ottoman sanjak.
