Editing Oil City, Pennsylvania (section)

===Post-charter Oil City===
The city was partially destroyed by flood in 1865 and by both flood and fire in 1866 and again in 1892; on this last occasion, several oil tanks that were struck by lightning gave way, and Oil Creek carried a mass of burning oil into the city, where some 60 people died and property valued at more than $1 million was destroyed. Oil City grew into a thriving community through the later half of the 19th century and into the 20th century. By the 1990s, Pennzoil, Quaker State, and Wolf's Head had all relocated their headquarters elsewhere. However, some oil wells continue to produce a steady supply of quality petroleum.<ref>accessed 10 March 2024, https://web.archive.org/web/20211024064949/https://www.mineralanswers.com/pennsylvania/venango-county</ref>

Regional governments and public organizations promote tourism by thoroughly educating the public about oil history.  Oil City's location along the Allegheny River in the foothills of the [[Appalachian Mountains]] provides excellent opportunities for exploring Northwestern Pennsylvania.

The [[Oil City Downtown Commercial Historic District]], [[Oil City North Side Historic District]], [[Oil City South Side Historic District]], [[National Transit Building]], and [[Oil City Armory]] are listed on the [[National Register of Historic Places]].<ref name="nris">{{NRISref|version=2010a}}</ref>
