Mount Airy Historic District
Also known as: Mount Airy Park; Prospect Avenue
Why it's listed
Mount Airy is a residential district of large, ornately detailed houses on Prospect Avenue in Bethlehem, built mostly between 1910 and 1930, with earlier houses from 1895 to 1909. Its 27 contributing residences show a range of revival styles, including Colonial, Tudor, French Renaissance and Spanish Revival, built in brick, stone, shingle and stucco. The lots were laid out in the late 1890s and early 1900s on a high ridge west of the city center, and the district developed as a suburban setting with deep setbacks, plantings and circular drives. Its importance rests on its link to the executives of Bethlehem Steel, the city's major industry, who bought and built here after Charles Schwab took over the company in 1904. The district is also regarded as the city's only large collection of early 20th-century high-style houses. Most of the houses remain largely unaltered, and the district is valued for its architecture and its role in the city's industrial history.
Significance in brief: The nomination argues the district is the only extensive collection of early 20th-century large, high-style houses in Bethlehem and was the principal residential enclave of Bethlehem Steel executives during the company's peak period. It is significant for its association with those leading executives and for its architecture, which includes Colonial Revival, Tudor Revival, French Renaissance Revival, Spanish Revival and Queen Anne examples.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
