This structure, built of local stone by the Works Progress Administration in the 1930s, marks the entrance to the limestone cave which gives the community its name. Two million gallons flow daily from the source, which has been a landmark since long before the establishment of the town in 1832.

In 1931 Dr. J. B. Rolater deeded the cave and 29 adjacent acres to the people of Cave Spring for use as a public park. In the early days local residents were allowed to tour the cave for free, while tourists were charged ten cents.
