Early map of Chicago issued shortly after the 1871 Fire.
The darkened portion of the map shows the Burned District consisting of 2,124 acres and containing 17,450 buildings.
A scarce map -- this is the first example we have offered.
The Great Chicago Fire was a conflagration that burned in the American city of Chicago on October 8–10, 1871. The fire killed approximately 300 people, destroyed roughly 3.3 square miles (9 km2) of the city, and left more than 100,000 residents homeless.
