Coral stone ruins are all that remain at the site that served mostly as a prison; however, the ruins are actually not the real leftovers from the fort. They were constructed as a set for the 1961 movie The Devil at 4 O'Clock. The real fort was built from 1831 to 1832 after sailors, angered by a law forbidding local women from swimming out to ships, lobbed cannonballs into town the previous year. The fort was finally torn down in the 1850s and the stones were used to construct the new prison. Cannons raised from the wreck of a warship in Honolulu Harbor were brought to Lahaina and placed in front of the fort, where they still sit today.
