The Barretts (of Wimpole Street fame) came to Jamaica in the 1660s and amassed great wealth from their sugar plantations. They built Greenwood in 1790 primarily for entertaining. Among the artefacts on display is the original library of the Barretts with books dating back to 1697; an extremely rare collection of musical instruments (all in working order); and the famous paintings that depict "The Lady in Grey."
