The Duquesne Gardens was the main sports arena located in Pittsburgh, Pennsylvania, during the first half of the 20th century. Built in 1890, the building originally served as a trolley barn, before becoming a multi-purpose arena. The Gardens opened three years after a fire destroyed the city's prior sports arena, the Schenley Park Casino, in 1896. Over the years, the Gardens was the home arena of several of Pittsburgh's historic sports teams, such as ice hockey's Pittsburgh Pirates and Pittsburgh Hornets. The Western Pennsylvania Hockey League, which was the first ice hockey league to openly hire and trade players, played all of its games at the Gardens. The arena was also the first hockey rink to ever use glass above the dasher boards. Developed locally by the Pittsburgh Plate Glass Company, Herculite glass was first tested in Pittsburgh. Most rinks were using wire mesh before the shatterproof glass was invented. Finally, the Pittsburgh Ironmen, a charter member of the Basketball Association of America (a forerunner of the National Basketball Association), played at the Gardens from 1946 to 1947. Outside team sports, the Duquesne Garden Ball Room, located on the arena's second floor, was also one of the largest dance halls in the country during the time.

Saint Nicholas Greek Orthodox Cathedral located at 419 South Dithridge Street in the Oakland neighborhood of Pittsburgh, Pennsylvania, was designed by architect Thomas Hannah and built in 1904. The First Congregational Church built the structure and used it until 1921, but it has been a Greek Orthodox Church since 1923. Currently, it is part of the Greek Orthodox Archdiocese of America, and seat of the Greek Orthodox Metropolis of Pittsburgh. This Classical Revival style church building was added to the List of Pittsburgh History and Landmarks Foundation Historic Landmarks in 1982.Architecturally, the cathedral is described by Walter C. Kidney in his book Landmark Architecture: Pittsburgh and Allegheny County (1985) as: A Grecian Ionic portico, executed in sandstone, is the grand and appropriate introduction to a church that has belonged to the Greek Orthodox Church since 1923. The exterior, with its big round-arched windows, is not otherwise specifically symbolic, but the interior is rich with paintings and mosaics. Notable inside are the painting in the dome of Christ the Pantocrator (Ruler of All), with its background of gold leaf, and the iconostasis of metal and mosaic, with peacocks finely depicted on the Royal Doors. Further art is to be found within the sanctuary, including a painting of the Mother and Child and a fresco of the Last Supper." Franklin Toker describes the structure in his book Pittsburgh: A New Portrait (2009) as follows: "Originally the First Congregational Church, until 1921, this is an unusually vigorous design in yellow industrial brick preceded by a dramatic Ionic portico. The interior of St. Nicholas should not be missed as an architectural paradigm of America itself: a cool Protestant interior heated up by a blazing iconostasis."

The Church of the Ascension is an Anglican church located at Ellsworth Avenue and Neville Street in the Shadyside neighborhood of Pittsburgh, Pennsylvania. It was built in 1898. The church was added to the List of Pittsburgh History and Landmarks Foundation Historic Landmarks in 1971.Like nearly all the Episcopal churches of the Pittsburgh area in the first half of the 20th century, the church boasted a really fine professional choir of men and boys that dominated the Sunday services, performing the music-heavy ritual of Morning Prayer from the 1928 Book of Common Prayer three Sundays out of four, the fourth Sunday being devoted to the celebration of Holy Communion. The choir's choral accomplishments peaked twice under the direction of Herbert C. Peabody in the 1930s and Robert Hamilton Cato in the 1940s. The church is currently a member of the Anglican Diocese of Pittsburgh, in the Anglican Church in North America.
