Wolf, Penrose, Building
Also known as: Rockwood Opera House

Approximate location: the National Park Service places this pin arbitrarily within the property, not at a surveyed point (stated accuracy ±12 m).
Why it's listed
Built in 1898 by Penrose Wolf as a lumberyard and feed store on Main Street in Rockwood, the two-story frame front section held an opera house on its upper floor, and a three-story brick addition followed in 1905 with six wooden grain hoppers, a railroad siding running through its basement, and freight doors lifted by cable. Wolf, a timber merchant and civic leader, sold lumber used in many local buildings and organized a water supply after a typhoid outbreak in the 1890s. The opera house hosted plays, vaudeville, minstrel shows and some of the earliest films shown in the area, including a 1906 screening advertised in the Rockwood Leader. The ground-floor office keeps chestnut paneling arranged in chevron patterns, a finish the nomination calls rare in Somerset County. The building continued as a feed store until 1992, and its grain bins, belt components and interior finishes remain largely intact.
Significance in brief: The nomination argues the building was a major commercial and entertainment center in early twentieth-century Rockwood, serving as a lumberyard, feed store and opera house. Its front interior retains intact chestnut paneling in chevron patterns, which the nomination describes as rare for the county, and its rear addition keeps working grain-handling components.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
