This historic property was laid out as lot number 36 in the original 1667 survey of Middletown village. Early owner James Grover Jr. erected the kitchen section of the structure in 1686, making it one of the oldest surviving structures in New Jersey. It was built in a salt-box shape with a large keeping room in front, and one or two smaller rooms behind. The house was greatly enlarged about 1762 into a center hallway residence with grandly paneled rooms on either side. The original cottage became the kitchen, and its salt-box shape determined the roofline of the new section. Edward Taylor took possession of Marlpit Hall in 1771. It remained in the hands of his descendants until 1930. The Georgian-style house, reflecting the lifestyle and taste of its occupants, is furnished with fine examples of 18th century furniture, many with histories of ownership in Middletown.
