The Alcoa Building (a.k.a. the Regional Enterprise Tower) is a 410-foot-tall (120 m) skyscraper in Downtown Pittsburgh, Pennsylvania. It was completed in 1953 and has 31 floors. It is the 15th tallest building in the city and is adjacent to Mellon Square. A unique radiant heating and cooling system is contained in the ceiling: since there are no pipes, radiators, or air conditioning units along the exterior walls, an additional 15,000 square feet (1,400 m2) of rentable space was gained. Also, the windows rotate 360 degrees so they can be washed from the inside.Originally the headquarters for the Aluminum Company of America (ALCOA), the unique aluminum walls of the building are 1/8 inch thick, which gives the building a very light weight and economical design. It was the first skyscraper with an all-aluminum facade. Upon ALCOA's 2001 relocation to a new headquarters building on Pittsburgh's North Shore near PNC Park, the old ALCOA Building became a home to government entities, regional nonprofits and small start-up companies including the RIDC.

The Harris Theater is a landmark building at 809 Liberty Avenue in Downtown Pittsburgh, Pennsylvania's Cultural District. The 200-seat theater is owned and operated by the Pittsburgh Cultural Trust. Built as Art Cinema, it was the first Pittsburgh venue to show only "art movies". In the 1960s, it featured pornographic films at a time when Liberty Avenue was a red-light district. The Pittsburgh Cultural Trust purchased and refurbished the theater as part of its plan for the Cultural District. In 1995 it was renamed The Harris with a gift from the Buhl Foundation, in honor of John P. Harris, who was a co-founder of the Nickelodeon—the first theater solely dedicated to the showing of motion pictures—and a Pennsylvania State Senator. The name "Nickelodeon" was coined by Harry Davis and John P. Harris, who opened their small, storefront theatre under that name on Smithfield Street in Pittsburgh in June 1905. Davis and Harris found such great success that their concept of a five cent theatre running movies continuously was soon imitated by other entrepreneurs, as was the name of the theatre itself.
