The flag of Pittsburgh, Pennsylvania, is a tricolor flag featuring vertical bands of black and gold, with the city's coat of arms in the centre.
In 2004, the flag was ranked 24th best flag design out of 150 city flags by the North American Vexillological Association, and was the top-rated tricolor.
In tribute to the flag, all four professional athletic teams in Pittsburgh in the sports of baseball, football, hockey, and soccer are black and gold. The arms are based on those of William Pitt, 1st Earl of Chatham, namesake of the city.
The phrase Benigno Numine was the motto of the Earl of Chatham. It is generally translated as "With the Benevolent Deity" or "By the Favour of the Heavens".
It was adopted by the newly formed city in 1816 but somehow fell off seals and official documents and emblems in the early 20th century before being restored to the seal by City Council on July 3, 1950 and signed off by the Mayor on July 7, 1950. However even then the motto was not implemented until council looked into the matter in November 1958.
The city of Pittsburgh's coat of arms is based on the arms of William Pitt, the first Earl of Chatham and the city's namesake. The crest of the city's coat of arms, an image of a fortress, represents the city of Pittsburgh, serving as a mural crown of sorts.
The official blazon of the city's coat of arms, as defined by a 1925 city ordinance, is as follows:
On a field Sable, a fess chequay Argent et Azure, between three bezants bearing eagles rising with wings displayed and inverted Or. For crest, Sable a triple-towered castle masoned Argent.
