=The Ohio Theatre's Air Conditioning System=

When the Ohio Theatre was built in 1938, engineers installed an unusual air conditioning system that was then state of the art.

Cold water is pumped from a private well behind the theater. This water is circulated through a huge series of coils. A huge six-foot fan then blows air across the coils which is then circulated through the building through a series of tunnels under the auditorium and behind the stage.

A recent tornado warning allowed movie-goers rare access to the catacomb-like tunnels below the theatre.
