Derinkuyu is situated 29km from Nevsehir, on the road to
Nigde. The settlement is approximately 85m deep. It
contains all the usual rooms found in an underground
(stables, cellars, refectories, churches, wineries etc.).
Apart from these, a large room with a barrel vaulted ceiling
on the second floor was a missionary school, the rooms to
the left being study rooms.
From the 3rd and 4th floors onwards the descent is by way of
vertical staircases which lead to the cruciform plan church
on the lowest floor.
The 55m deep ventilation shaft was also used as a well. Not
every floor was provided with a well, however, some wells
were not connected with the surface in order to protect the
dwellers from poisoning during raids. Derinkuyu Underground
settlement was opened to visitors in 1965, but so far only
10% can be visited.
