Photos of the Great Boston Fire of 1872.

The Great Boston Fire of 1872 was Boston's largest urban fire, and still ranks as one of the most costly fire-related property losses in American history. The conflagration began at 7:20 p.m. on November 9, 1872, in the basement of a commercial warehouse at 83-87 Summer Street. The fire was finally contained 12 hours later, after it had consumed about 65 acres (26 ha) of Boston's downtown, 776 buildings and much of the financial district, and caused $73.5 million in damage. At least 30 people are known to have died in the fire.
