Callowhill Historic District
The Callowhill Historic District covers the nine-block corridor of Fifth Street from Buttonwood Street south to Laurel Street, and from 348 Penn Street to 601 Penn Street. The 253 acre historic district derives its name from the maiden name of William Penn's second wife, Hannah Callowhill Penn, mother of Thomas and Richard Penn who founded the City. Fifth Street had originally been designated "Callowhill Street" in her honor. As the core of the district is one of the first areas developed in the City, and a diverse collection of residential and commercial architecture from the early to late nineteenth century is represented.
