In one of the oldest stone buildings on the islands, the national museum houses the Molasses Reef wreck, the earliest shipwreck—dating to the early 1500s—discovered in the Americas. The natural-history exhibits include artifacts left by Taíno, African, North American, Bermudian, French, and Latin American settlers. The museum has a 3-D coral reef exhibit, a walk-in Lucayan cave with wooden artifacts, and a gallery dedicated to Grand Turk's little-known involvement in the Space Race (John Glenn made landfall here after being the first American to orbit the Earth). An interactive children's gallery keeps knee-high visitors "edutained." The museum also claims that Grand Turk was where Columbus first landed in the New World. The most original display is a collection of messages in bottles that have washed ashore from all over the world.
