The fortress was constructed on a natural basaltic rock formation, often referred to as a volcanic plug.
The structure contains ancient cisterns carved into the rock that were used to store water during prolonged sieges.
Archaeologists have identified distinct layers of masonry from the Pontic kingdom, Roman Empire, and Byzantine periods.
The fortress functioned as a key defensive node for the Danişment Beylik during their expansion into the region.
The site remains largely unexcavated, leaving many subterranean passages and secondary structures unexplored by modern researchers.
Unye Fortress, locally known as Unye Kalesi, is an ancient volcanic fortification situated on a steep hill approximately seven kilometers inland from the Black Sea coast. The site dates back to the Pontic Greek period and served as a strategic military outpost throughout the Roman and Byzantine eras. It is characterized by its dramatic position atop a monolithic rock mass that rises sharply above the surrounding valley. Visitors can explore the remnants of ancient walls, cisterns, and rock-carved structures built directly into the basalt bedrock. A series of stone stairs and narrow passages facilitate movement through the ruins, which provide visibility over the historical trade routes connecting the coastline to the interior. The fortress is currently maintained by local authorities as an archaeological site open for public hiking and historical exploration.

Wear sturdy hiking boots with aggressive tread, as the stone steps are steep, uneven, and can be slippery.
Bring a high-powered flashlight to safely inspect the dark rock-carved tunnels and interior chambers.
Carry sufficient water, as there are no amenities or vendors available within the fortress grounds.
Do not attempt to climb the exterior rock faces; use only established paths to reach the summit.
Practice leave-no-trace principles; do not climb on unstable wall sections or remove stones from the site.
