The rock houses were carved into volcanic tuffs that are relatively soft when moist but harden significantly when exposed to air.
Architectural analysis suggests the complex was built vertically to provide protection from floods and wild animals.
Many of the interior walls still retain faint traces of historic wall paintings and functional niches used for oil lamps.
The structure acts as a natural insulator, maintaining a stable internal temperature regardless of external weather conditions.
Some chambers were historically used for grain storage, featuring stone-carved pits designed to keep moisture out of the harvest.
The geological formation is part of a wider corridor of historic settlements stretching toward the ancient Phrygian Valley.
The Seben Rock Houses are an ancient multi-story cave settlement carved directly into the volcanic tuff cliffs of the Solaklar village in Bolu, Türkiye. The site consists of interconnected rooms, galleries, and storage areas spanning several levels, accessible via narrow rock-cut stairs. Historically used as a defensive dwelling and granary during the Phrygian and Byzantine periods, the complex demonstrates advanced ancient architectural techniques for climate control and security. Visitors can explore the preserved living chambers and corridors that characterize this cliffside urbanism. The site is situated within the Aladağ mountains region, known for its unique geological formations and deep history of cave-dwelling cultures.
From the base of the cliff looking upwards to capture the multi-level verticality of the cave openings.
Wear sturdy, closed-toe hiking shoes with high-grip soles as the stone paths can be slippery and uneven.
Carry a high-powered flashlight to see into the darker recesses and interior chambers that lack natural light.
Avoid touching the soft rock walls to help preserve the fragile, ancient carvings from further erosion.
Do not attempt to climb the exterior cliff face outside of designated paths, as the volcanic rock is prone to crumbling.
Respect the archaeological site by refraining from carving names or climbing on fragile cliff edges.
