This lion-faced manhole cover design marks the location of The Benedum–Trees Building on Fourth Avenue in downtown Pittsburgh, Pennsylvania. The nineteen story building was built in 1905 by Caroline Jones Machesney, and was called the Machesney Building until 1913 when she sold it to Joe Trees and Michael Late Benedum, founders of the Benedum Trees Oil Company who had relocated their business headquarters in the city. A lion is a symbol of power, wealth and protection and can be seen in many places on architecture along Fourth Ave. In this spot it may also represent the Benedum Trees reputation as successful "wildcatters" in the oil industry, finding oil in new and previously untapped areas.
