This building, in the heart of downtown Boston amidst very modern skyscrapers, was once the home of Chadwick Lead Works (obviously). Given that it was built in 1887 it was amazing (and rather charming) to see it standing in a modern downtown area.
This shot is a panoramic stitch of five frames taken from the sidewalk across the street. I would shoot one frame then move down the sidewalk a bit to take the next shot. Having been stitched from several frames you can zoom in and see quite a bit of detail (click the image to get to flickr where you can view the larger size).
