The 1852 Hunt · STOP 04 · Downtown Crossing
The Great Fire started in a basement on this corner, and no photograph of it burning is known to exist.
The Great Fire of 1872 burned 776 buildings across 65 acres of downtown Boston, and no photograph of it burning is known to exist - only the ruins, afterward. It started in a basement on a Summer Street corner just after seven on a Saturday night. A plaque marks the spot and puts a price on the damage. The fire historians use a different number.

Directions
The inquiry heard about mansard roofs dozens of times. One witness: 'This whole fire is the result of the architects being allowed to pile up their Mansard roofs.' Low water pressure made the top floors and roofs hard to reach, the BPL says.
