Warren, Pennsylvania: Lumber, Oil, and the Allegheny

Warren was laid out in seventeen ninety-five and named for General Joseph Warren, the patriot physician killed at Bunker Hill. It sits where the Conewango Creek flows into the Allegheny River, and for the first half of the nineteenth century its economy ran on logs, timber floated down the Allegheny to Pittsburgh markets. That changed in eighteen seventy-five when a driller searching for natural gas on an estate east of town struck oil instead.

Warren's entire character shifted within a decade: oil tycoons, refiners, and bankers built the Victorian-era houses that still line the residential streets today. The prosperity lasted through World War Two. Warren remains a small city of about nine thousand, its architectural heritage from the oil years largely intact, the Allegheny still running along its edge.
