My thanks to David Emery for sending in this photo from the A. D. White Architectural Photographs, Cornell University Library (Accession Number: 15/5/3090.00452) of the Pompeia at Saratoga Springs. Other images from the Pompeia can be seen here on Flickr.
These are fabulous photos and I want to know more! Is the Pompeia still standing? Can it be visited? Who built it and why? Can anyone provide any details about this?
