Local features 
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 borough 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.
