The Capewell Horse Nail Company is a historic brick industrial complex located in the Hartford, Connecticut neighborhood of Sheldon/Charter Oak. It was built in 1903 by industrialist George Capewell at the corner of Charter Oak Avenue and Popieluszko Court after the previous headquarters burned down.
Twenty years earlier, in 1881, Capewell invented a machine that efficiently manufactured horseshoe nails, and his success made Hartford the "horseshoe nail capitol" of the world.
The factory building includes a Romanesque Revival-style square tower with brick corbeling and a high pyramidal roof. The administration building is Hartford’s finest example of Dutch architecture with highly articulated brick and brownstone details. The Jacobean front gable is detailed with elaborately patterned brickwork not found elsewhere in Hartford.
The company was acquired by Hartford/Standard Machine Screw Company in 1970 and operated as a subsidiary. A few years later Standard Screw became Standadyne Corporation, which ceased production at the plant and sold the real estate in 1981, a century after the company had been formed. Capewell continued to manufacture horsenails and other products at its Bloomfield facility until its closure in 2012.
The Corporation for Independent Living, a non-profit housing group, acquired the property in 2014 and plans to convert it into apartments. The property was listed on the National Register of Historic Places in 2000.
