Winnekenni Castle – Haverhill, Massachusetts - Atlas Obscura

Inspired by the structures and castles in England, the chemist James Nichols built a castle with 35,000 cubic feet of glacial boulders in Haverhill, Massachusetts.  The castle was erected between 1873 and 1875 as a retreat home for summer time and it was named Winnekenni, an Algonquin word meaning “very beautiful.”

Nichols treated the castle’s construction as an experiment. He was determined to prove that rocks and boulders could be a good source of construction material for farms and other buildings in the county. He published a book based off his experience in 1876 called, Boulder Rocks: Their Probable Origin and History and their use in the Construction of Dwellings.

Winnekeni Castle stands about 250 feet above Kenoza Lake, and has a spectacular view of some adjacent towns and county. As is typical for a summer house, the interior of the castle has some unique architectural features including a gothic door, a Pompeian dining room, a library, nine bedrooms, a bathing room, and four towers with roof access. Outside, an extensive lawn surrounds the building.

In 1885, the castle changed hands from Nichols to his cousin William Webb. Ten years later it was sold to the city of Haverhill, and became the first public park in the area. Its elaborate Victorian interior was destroyed by a fire in the late 1960s, but the exterior stood strong. Today, Winnekenni Castle is part of over 700 acres of conservation land known as Winnekenni Park Conservation Area, which also includes some nine miles of hiking trails.
