Westmoreland County Courthouse
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
Greensburg's county courthouse, at the corner of Main and Pittsburgh Streets, is a four-story building with a central dome rising 175 feet above ground and flanking gable-roofed wings. Completed in 1906-7 and dedicated in January 1908, it was designed by William Kauffman, an architect from Pittsburgh. Its exterior is faced with light gray granite from Maine, and the small domes and main dome are covered in gold and ivory terra cotta. The east entrance has a large pediment carved with figures representing Art and Industry. Inside, the rotunda rises through four floors, with walls of English-veined Italian marble, colored marble mosaic floors, a marble grand stairway, and mahogany and white oak woodwork. The building is significant as an ornate example of the Beaux Arts style and as a work of an architect whose dome design was rarely built. It succeeded earlier courthouses on the same site, the first a log structure that served until 1801.
Significance in brief: The nomination argues the courthouse is an impressive example of the Beaux Arts style, notable for its ornate gold glazed dome, decorative carving and statuary, and interior finished in marble and fine woods. It describes the dome as one of only two of its design built by its architect, William Kauffman.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
