What if? Rethinking the Gasholder, and Concord's future...
It is the first building that draws your attention as you approach Concord, NH, from the highway. It towers above the State Capital skyline like a Renaissance-era Italian fort, a cathedral, or an opera house. It is the last of its kind, and its days may be numbered. It is an 19th century brick Gasholder – and its future is not clear. Its owner, Liberty Utilities, has said it plans to secure a demolition permit at the end of this month.
Concord’s Gasholder is a tie to an industrial technology that created dynamic growth in the country. It is one of only 14 gasholders left in the country AND the only one that still has the internal workings intact. Also, it's listed on the National Register of Historic Places.
The Concord Gas Light Company Gasholder House was built in 1888 to feed a booming city with gas for lighting and heat. A gasholder, or gasometer, was a large structure in which natural gas or town gas is stored near atmospheric pressure at ambient temperatures. The volume of the container follows the quantity of stored gas, with pressure coming from the weight of a movable cap.
