Cappadocia,
Unique Land of Caves
Cappadocia is Turkey's land of pure amazement, an
extremely popular region for tourism.  Volcanic rock led to
all these wonders, because it could easily be carved into caves
and underground cities.  This is the Kale, a rock castle in
Uchisar, full of tunnels and caves that were once used for
housing.  It's now unoccupied and open to tourists.  I was
perfectly satisfied with this wide shot of the Kale, including
actual houses lying beneath it.  Kale is an unusual
neighbor.

Nearby is the Goreme Open-Air Museum, full of caves
that were used by early Christian communities.  They
needed protection from invading armies, and found it
by carving into the rock.
This is the opening to a Christian cave church.  You can
see the crosses which are prominently displayed.
Inside one of the cave churches, it is still possible
to make out a 1,000 year old Christian fresco.
When truly threatened the Christians retreated into
underground cities which they had carved.  This is
Derinkuyu, which means "deep well".  It went down eight
levels.  On the left is a barrier rock which rolled right to
block the entrance.  It worked and entire communities
survived by literally going underground.
