The Haymaker Gas Well in Murrysville was the nation's first commercial natural gas well. For some time, it remained the largest commercial gas well in the world.
Since 1933, Murrysville has had a "tree sign" spelling out the word "Murrysville". The trees were landscaped to grow and form the letters by local Boy Scouts. The sign is situated on a large hill as one enters the Municipality from the Murrysville–Monroeville border, near U.S. Route 22. In 1947, the sign was featured in "Ripley's Believe It Or Not" as the world's largest arboreal sign. (It is no longer the world's largest, or even the largest in the country; "Luecke", near San Antonio, Texas, is much larger.) The "Y" in the Murrysville sign points to the Haymaker Gas Well.
In 1977, Murrysville was designated the "Gateway to Westmoreland County" by Mayor Dollman in conjunction with the Chamber of Commerce. In 2012, community leaders upgraded sign and landscaping elaborately at the main entrance at the Allegheny / Westmoreland border featuring this designation. As is shown at the introduction of this page, the Gateway designation is featured on the official Seal of the Municipality.
