The Retreat House and Dock of Penn Center, formerly known as Penn School, was built in 1968, the year Dr. Martin Luther King, Jr. was killed. Plans were for him to have his meetings there rather than the smaller Gantt Cottage he had been staying at. It faces a body of water, a cove of Capers Creek, which is a place for meditation and relaxation for Penn Center's guests. The Retreat House replaced the Palmetto Cottage built in 1920 which was formerly located at this site but was destroyed by fire in the 1950s. The Retreat House and Dock was however used by Dr. Martin Luther King, Jr.'s associates during the Charleston Hospital Strike of 1969.
