Fodor's Expert Review Smith's Castle

Originally the site of a trading post established by Roger Williams, founder of the Rhode Island colony, the Smith's Castle grounds include a marked mass grave where 40 colonists killed in the Great Swamp battle of 1675 are buried. The land just outside Wickford village was part of a large plantation during the 18th century, spanning more than 3,000 acres worked by tenant farmers and—yes, even in Rhode Island—enslaved people and indentured laborers; later, it became a large dairy farm. Saved from the wrecking ball by preservationists in 1948, the beautifully preserved saltbox home—one of the country's oldest plantation houses—appears much as it did in 1740. Docents in period costume provide interpretive tours of the house several times a day, Friday through Sunday from May to mid-October.
