First the honorable mentions in no particular order.

Gary Freegard: There is a disorienting feel to this space that appeals, plus the lighting is really great.

Luxun54: The lighting streaming through really makes this shot special, and what a location.

J Rayner: A well chosen perspective literally captures the electricity of this place. The distortion works well here to enhance the feeling of space and power.

Third Place: Markus: An interior like no other. Wonderful details and exposure. I really like the placement of the globe and lights.

Second Place: Dennis: A chilling photograph of this Asylum. Really brings home the horrors of this place.

First Place: Terry: I really like the complexity of this interior from this well chosen vantage point. This image works so well on so many different levels.
My Best Wishes to you all, Walter
