Editing Pennsylvania Hospital (section)

=== Early Development ===

The hospital opened in a temporary location on Market Street in 1752, admitting its first patient that year. Construction of a permanent facility began in 1755 under the direction of Samuel Rhoads, a master builder and member of the Carpenters' Company who drew inspiration from the Royal Infirmary in Edinburgh.

The East Wing was completed in 1756, followed by the West Wing in 1797, and the Center Building in 1804. Together, these sections form the Pine Building, one of the finest examples of 18th-century American colonial architecture.
