Addison Blockhouse Historic State Park

The Addison Blockhouse was built on a 19th-century plantation called Carrickfergus, established by John Moultrie. The blockhouse was originally an outside kitchen for Moultrie's overseer. Later the plantation was owned by John Addison, and then Duncan McRae. The plantation grew cotton and sugar from 1816 to 1836. During the Second Seminole War, the plantation was attacked on March 10, 1836. Two soldiers were killed and scalped at the site. The blockhouse was fortified by the Carolina Regiment of Volunteers to defend against the Seminoles, and became known as "Camp M'Rae".^[3] The plantation struggled financially and was later abandoned. The blockhouse was restored in the early 20th century, and has since been owned and maintained by Tomoka State Park.^[1][4][5][2]

The Addison Blockhouse is now a roofless ruin. It is about 11.5 ft (3.5 m) by 15 ft (4.6 m) in size. It contains a circular tower in one corner, 6 ft (1.8 m) in diameter and 11 ft (3.4 m) in height, as well as a large fireplace. It has six foot walls with an embankment and moat.^[1][2]

There is also an adjacent foundation and walls of a sugar mill from 1832 during the time McRae owned the plantation.^[1]
