Darrah Hall is the oldest building on the campus of the Penn Center, and is the park's base of operations for the Penn Center National Historic Landmark District.
Pinckney-Porters Chapel is a Reconstruction era Freedman's Chapel located in the Naval Heritage Park just outside the main gate to Naval Hospital Beaufort. The Town of Port Royal rebuilt the chapel in late 2020, and through an agreement, Reconstruction Era National Historical Park operates the site as a visitor contact station. Inside are temporary exhibits, and most Camp Saxton programs begin at this site. Pinckney-Porter's Chapel is open Fridays and Saturdays from 9am to 5pm.
The visitor center contains exhibits and information about the Reconstruction era in the low country, as well as information about visiting the various units of the park.
