Cantilevered over the rushing waters and waterfall of Bear Run, his most well-known work and architectural masterpiece, Fallingwater, is the ultimate showcase of Wright’s unique ability to seamlessly connect architecture with its environment. In 2019, it was inscribed as a UNESCO World Heritage site.

3. Kentuck Knob


Just six miles from Fallingwater is Kentuck Knob, one of the last homes completed by the country’s greatest architect, Frank Lloyd Wright. Both dramatic and serene, the house is situated just below the crest of a hill, making it appear almost part of the mountain itself with cantilevered overhangs and great expanses of glass.

4. State Capitol

Using steel and stone, Charles Klauder erected the Cathedral of Learning — a Gothic building of sweeping proportions on the University of Pittsburgh campus — to symbolize that “education was the result of aspiring to new heights.” The 535-foot-tall Cathedral has maintained its status as the tallest educational building in the U.S. and the second-tallest in the world. Take a virtual tour of the building’s 30 renowned international rooms.

6. Mellon Hall of Science


The rigorous simplicity of architect Ludwig Mies van der Rohe can be seen at Duquesne University’s Mellon Hall of Science. Overlooking the Monongahela River, the building is considered one of Pittsburgh’s top architectural gems, showcasing the famed architect’s use of austere building materials and totally symmetrical Modernist design. The building is still in use today by faculty and students in the school’s chemistry and biochemistry department.

7. City Hall

8. Erdman Hall Dormitories

Bryn Mawr

Architect Louis Kahn believed that his Erdman Hall Dormitories, a dormitory for girls built on the campus of Bryn Mawr College, should be designed less as a dorm and more as a house. The modern Scottish castle constructed of slate and concrete contains three connecting units or square structures with inner public spaces and outer student rooms.
