The castle is carved entirely into a single monumental volcanic rock mass, a characteristic style of the Phrygian period.
The structure includes an elaborate internal drainage system and multiple cisterns for water storage.
Many of the carved rooms feature 'couches' or benches cut into the rock, typical of Phrygian domestic architecture.
The interior layout spans several floors, connected by narrow, steep rock-cut stairs.
The site overlooks a valley that was once a major transit route for ancient civilizations connecting the Aegean to Central Anatolia.
Avdalaz Castle is a multi-story rock-cut fortress carved into a volcanic tuff formation within the Phrygian Valley near Ayazini. The structure features a complex network of chambers, grain silos, cisterns, and staircases carved directly into the rock face. Occupied during the Phrygian, Roman, and Byzantine periods, the site served as both a defensive stronghold and a residential complex. Unlike traditional built-up stone castles, it utilizes the natural topography to create concealed living spaces. The interior reveals carved shelves, niches, and functional architectural elements that indicate centuries of human habitation. The site remains largely uncurated, allowing visitors to walk through its various levels and tunnels. Its remote location in the Afyonkarahisar region helps maintain its original state against modern development.

Wear shoes with excellent grip as the volcanic tuff surfaces can be slippery and uneven.
Bring a high-powered flashlight to explore the darker, deeper interior chambers safely.
The interior is not climate-controlled and can be significantly cooler than the outside air temperature.
Do not attempt to climb the exterior faces of the rock; stick to established interior paths and entryways.
Avoid carving your name into the rock walls; the site is a protected historical monument.
