A Florida Historical Marker was placed at the River Park Inn (formerly Cottage A at the renowned Clarendon Hotel) at 103 S. Magnolia Ave. in Green Cove Springs last Saturday, May 18, to honor the work of Dr. Joseph Applegate, who came to Florida with the Freedman’s Bureau after the Civil War. He was the house physician at the Clarendon Hotel, where he lectured on the benefits of sulfurous water from the nearby spring. News spread of Applegate’s magic elixir, and Green Cove Springs became a popular vacation spot for northerner. Clamour Theatre presented a one-man play, acted by Micheal Zelenka, to tell Applegate’s story during the dedication. The marker, Dr. Applegate’s House, is the 21st historical marker in Clay County.
