The industrial and commercial activity in the 11 block area now known as the Powerhouse Arts District has been historically significant, not only to the Jersey City economy, but also to the regional and national economy, from the post-Civil War period until the Great Depression. The district was tied to the Pennsylvania Railroad yards (to the north, in what is now BJ’s parking lot) by railroad spurs; the remnants of these can still be seen on Provost Street. In the district’s heyday, some of the world’s largest manufacturers, wholesalers and retailers built here. Currently the Powerhouse Arts District is being redeveloped as a vibrant, arts neighborhood with adaptive reuse of existing warehouses.
