Museum of Antigua and Barbuda.

Housed in the 1750 colonial courthouse—the oldest surviving building in Saint John’s—the Museum of Antigua and Barbuda double-packages history, displaying the country's heritage inside a piece of it. This compact, survey-style museum can be thoroughly explored in under an hour, making it an ideal first stop to gain context on the islands. Exhibits trace a complete arc from geological formation and pre-Columbian Arawak life—complete with a life-sized replica of an indigenous house—through the brutal era of sugar plantations and slavery, up to modern cultural achievements. Upstairs, a public research library holds historic maps and photographs, while the ground-floor gift shop sells authentic local pottery and books, offering a thoughtful alternative to standard cruise-terminal souvenirs.
