Mount Lebanon is a township, technically speaking; but it feels more like a city of its own. Post-Gazette columnist Peter Leo always referred to it as “the Great State of Mount Lebanon,” which sums up how Pittsburghers think Mount Lebanese think of themselves. The central business district is “uptown”—a word that means an area outside downtown in most cities (even Pittsburgh itself), but in southwestern Pennsylvania usually means a downtown area that happens to be on a hilltop. Uptown and the surrounding area is now a national historic district, and this 1930 Art Deco building is one of its gems: it is the masterpiece of its architect, William Henry King, Jr.
A decade-old article from the Trib has quite a bit of good information about the building.
