"Capital city" may bring to mind a bustling metropolis, but you'll find that it couldn't be further from the truth for Kingstown, on St. Vincent. "Laid-back port city" is more Kingstown's speed, and its London-style historical structures seem content to turn things back a century or two. The architecture has earned it the nickname "City of Arches" for the distinctive triangle shape you'll find on the façade of its typical Georgian-style buildings. The tropical climate makes St. Vincent hospitable for botanical gardens and plantations of fruits like nutmeg and breadfruit, grown in the island's rich volcanic soil. You can actually pick some up at Kingston's lively markets, in addition to the crafts and keepsakes, handmade jewelry and more treasures.
