Moffatt-Ladd House

Moffatt-Ladd House is at 154 Market St. on the Portsmouth Harbour Trail. Best known as the home of William Whipple, a signer of the Declaration of Independence, the house was built in 1763 by Whipple's father-in-law, John Moffatt, a wealthy sea merchant. Paneled halls and chambers, an ornate staircase and original furniture distinguish the house, which is set amid formal gardens with turf steps and raised beds.
