This tiny 18th-century building of cypress and cedar served not only as a schoolhouse but also as a tearoom, a farmhouse, and a guardhouse and sentry shelter during the Seminole Wars. In 1939, members of the Class of '64 (1864, that is) dressed out the school as they remembered it, and today automated mannequins instruct you on the education of 150 years ago. Apparently teachers had more leeway then because miscreants were given "time out" in a cubby beneath the stairs.
And the heavy chain wrapped around the building? It was to hold the structure down during hurricanes. Kids will like the school bell and wishing well in the charming courtyard garden.
