Concord Gas Light Company Gasholder House, Industrial gasholder house in Concord, United States.

The Concord Gas Light Company Gasholder House is a cylindrical brick building with a cone-shaped roof located on Gas Street. Inside sits a large tank that once stored the gas needed to light homes and streets across the town.

The Concord Gas Light Company built this structure in 1888 to store processed coal gas for the town's supply needs. It served as a key part of the gas distribution network that brought light to homes and public spaces.

The structure stands as a testament to nineteenth-century industrial engineering, representing the evolution of municipal gas storage and distribution systems.

The building sits on Gas Street and can be viewed from the outside, though it is not open for public access inside. The structure underwent stabilization work in 2022 to secure its future and prevent further deterioration.

The building retains its original internal wrought-iron gas mechanism, a system that no longer exists anywhere else in the country in this form. This technical detail makes it a rare example of how industrial gas storage actually worked in the 1800s.
