This is a 16-frame multi-row panorama, stitched together for an extremely wide angle view. Note that the top of the arch is not at the top of the picture; look for the windows which are centered at the top of the arch.
16-frame panoramic, stitched with PTAssembler, PanoramaTools, and Enblend. Photoshop for minor corrections and cloning, and fixes that Enblend was less than perfect on. NeatImage for noise reduction.
