The Gardner-Pingree House is now owned by the Peabody Essex Museum. It was built in 1804-1805 by John Gardner, Jr., who was a local merchant. It was later owned by Captain Joseph White. He lived in the house with his family until they were brutally murdered in the house in April 1830. In 1834, David Pingree owned the house. He and his heirs lived there until 1933.
The house is also known as the Turner-Ingersoll Mansion, named after the two families who lived there. It was built in 1668 by the Turner family, it is the oldest surviving 17th century wooden mansion in all of New England. After one of the Turner sons lost the family fortune, the Ingersoll family purchased it.
Today many believe the house is haunted by the White family. People claim to see ghostly faces looking out of the second floor windows, and many hear ghostly footsteps while touring the house. Some even claim that the grisly murder is reenacted on the anniversary of their death.
Many claim that the Custom House is haunted. There have been reports of people hearing the voices of ship captains talking about their treasures. Others have heard footsteps, seen strange lights, or even floating orbs. The ghostly visitors aren't mentioned on the tour :)
During the Gettysburg Battle, Confederate sharpshooters used the attic to target Union soldiers. Many believe it was one of these sharpshooters who accidentally killed Jennie Wade. Today those soldiers haunt the attic, and I guess they are very active. Just about every room in the house is haunted though, it gets so scary some visitors can't even stay there through the night!
Many people believe the Haydenville Tunnel is haunted by men who died while building it. They claim to see strange lights or even apparitions of these men dressed in work overalls. Many also claim to hear the sound of carts being pushed through the tunnel.
