Bear's Retreat is a small Pennsylvania landmark, primarily known for its age. It is a privately owned house dating back to c. 1794, being lived in as of 2011. The southern log side was built by Jacob Bare in 1794. It is believed he was a German immigrant based on the three-story construction of the log section. Despite plenty of room to build his home, large, heavy, hand-hewn logs were raised higher and higher into place in the traditional building custom of his homeland. The Northern "new addition" brick side built in 1840. The red-brick exterior was made on-site using the abundant clay found on the property. Remains of the outdoor summer kitchen are still clearly present. The property was designated a Pittsburgh History and Landmarks Foundation Historic Landmark in 1983. Bear's Retreat is at 253 Inglefield Drive, Pleasant Hills, Pennsylvania.

Experimental Mine, U.S. Bureau of Mines is a landmark located in the Pittsburgh suburb of Bruceton, Pennsylvania. In 1910, the newly created U.S. Bureau of Mines leased a 38-acre tract of land from the Pittsburgh Coal Company and opened the Experimental Mine. One of the early findings in the Experimental Mine demonstrated that coal dust by itself was capable of propagating an explosion even in the absence of any methane gas. This demonstration was contrary to the old belief widely held at the time that coal dust could not explode without gas. This view had led to the very dangerous and widespread practice of using loose coal dust in mines to pack explosives in boreholes, which had cost many thousands of lives. These early experiments clearly proved that such a practice was too hazardous to continue.

Allegheny County Airport (IATA: AGC, ICAO: KAGC, FAA LID: AGC) is in West Mifflin, Pennsylvania, United States, 7 miles (11 km) southeast of Pittsburgh. It is the fifth-busiest airport in Pennsylvania following Philadelphia, Pittsburgh, Allentown, and Harrisburg. The airport is owned by the Allegheny County Airport Authority and is the primary FAA-designated reliever airport for Pittsburgh International Airport. Allegheny County Airport was dedicated on September 11, 1931.When it was completed, it was third-largest airport in the country and the only hard-surface airport in the country. It was historically the main entrance to metro Pittsburgh via air from its inception until June 1952, when the Greater Pittsburgh Airport (now Pittsburgh International Airport – KPIT) opened for commercial aviation. Like many historic municipal fields, Allegheny serves small and mid-sized private, corporate and commercial traffic well, but was not built to handle jet airliners. A Boeing 727 owned by Rockwell and two DC-9's however were based on the field for years. One DC-9, owned by Westinghouse Air Brake, operated from the former TWA hangar. Another DC-9 was owned by Richard Scaife. Additionally, political candidates often operate chartered jet airliners into the field. Air Force 2, a Boeing 757, has been on the airport in the 2000s. In May 2017, a Southwest Boeing 737 with 143 passengers en route from Orlando, made a precautionary landing when running low on fuel. The airport is popular among business travelers, being closer to downtown than Pittsburgh International Airport. It is much closer to the densely populated South Hills, Monroeville area and Monongahela Valley. The airport is home to Pittsburgh Institute of Aeronautics (PIA), a large aircraft maintenance school.
