Roman Bridge at Ronda, Spain

Note:  The above bridge was not really built by the Romans.
However, it was built on the site of a Roman Bridge, and a lower
bridge serves the community in the valley.  At one time, several
years ago, there was a restaurant in the bridge, the dinung room
being in the center part of the bridge at the point just above the
center arch.  The dining room was set up in what used to be a
prison.  The only way out of the prison room was to have a rope
lowered into the room from the road above.  Of course,
in the present day, a passage was built into the prison room
 for the diners.
