The Bailey Farm is an historic farm at 373 Wyatt Road in Middletown, Rhode Island. Now reduced from more than 100 acres (40 ha) to about 45 acres (18 ha), the farm is a well-preserved example of a 19th-century island farm. It was owned by members of the Bailey family, possibly as early as the late 17th century, into the 19th century. The original main house appears to be a mid-18th century structure that was given a significant Greek Revival treatment in the 19th century. It is a 1-1/2 story Cape style house, three bays wide, with a central chimney. The main entrance is centered on the northern facade, and is flanked by sidelight windows and pilasters, with an entablature above. The corners of the building are pilastered. A series of outbuildings stand nearby. There is a second complex of buildings on the northwest part of the property, built in the 1930s near the location of the Bailey family cemetery.The farm was added to the National Register of Historic Places in 1984.

Boyd's Windmill, also known as Boyd's Wind Grist Mill, is a historic smock mill at Paradise Valley Park on Prospect Avenue in Middletown, Rhode Island. John Peterson built the windmill at the corner of Mill Lane and West Main Rd. in Portsmouth, Rhode Island in 1810, and William Boyd purchased it in 1815. It originally had four common sails, but four more were added by the family. The mill is a timber-frame structure, octagonal in shape, and about 30 feet (9.1 m) tall, with a rotating cap powered by eight vanes with canvas sheets. The grindstones in the middle of the mill are Fall River granite; the upper one, which is connected to the power mechanisms, rotates six times for each turn of the mill's main shaft. In 1916 Benjamin Boyd removed the original vanes and powered the mill using a gasoline engine.
