"97 Bridge Street, at the N.E. corner of York Street, showing also the Brooklyn Union Gas Co. tank on York Street." The frame building at the corner was recently demolished. Notice the architectural palimpsest on the building at the left.

A palimpsest is traditionally a parchment made from animal hide that has been scraped "clean" again so that new text can be written on it. In many cases the ghost of the original text can be seen faintly behind the text words. In the case of architecture, a palimpsest is the partial remains or outline of a vanished building seen on existing buildings.
