Cappadocia Tunnel Network — Subterranean Architecture

Cappadocia, Türkiye — An underground urban network with defensive geometry, airflow logic, and scale that makes it ideal for the first-launch Ancient Structures loop.

Derinkuyu alone sheltered thousands, with rolling stone doors, ventilation shafts, and levels that keep extending past every survey. The file tracks who the builders were hiding from, how deep the network truly runs, and which passages remain unmapped.

What this file needs: survey depth data · ventilation studies · connection-tunnel evidence.
