City Cemetery
This was the site of the City Cemetery, Chicago's only public graveyard from 1843-1859. Extending from North Av. to Wisconsin St., there were more than 20,000 burials here.
For nearly twenty years beginning in 1866, as the grounds were converted to Lincoln Park, bodies were being exhumed and carried to new private cemeteries outside city limits.
Since the 1890's construction projects have been revealing skeletal remains. For various reasons, many bones likely still remain here beneath the soil.
