Gasholder house
Building that encloses a gasholder / From Wikipedia, the free encyclopedia
A gasholder house is a type of structure that was used to surround an iron gas holder, also known as a gasometer, in which coal gas was stored until it was needed. There are approximately a dozen of these structures—most constructed of brick in the latter-half of the 19th century—that still stand in the United States. Some examples still stand in Europe as well.
