Philadelphia Register of Historic Places

The Philadelphia Register of Historic Places is an inventory of properties that have been designated as historic by the Philadelphia Historical Commission. Today, all properties go through a nomination process before being added to the register.

The register is split into three documents that include:

  • Properties with OPA-compliant addresses. These properties have official addresses that are recognized by the Office of Property Assessment (OPA), such as 237–49 Arch Street.
  • Properties without official addresses, such as the Valley Green Inn. These properties instead use approximate addresses.
  • Public interiors, objects, and structures. For example, the Grand Court of the Wanamaker Building interior.
