Founded in 1735 by Swiss immigrant Hans Bucher, Denver began as “Bucher’s Thal”—Bucher Valley. The settlement sat in the valley formed by Cocalico Creek and Little Cocalico Creek, surrounded by fertile soil and limestone formations that settlers quarried for construction materials. When the Reading and Columbia Railroad built through town during the Civil War, residents renamed it “Union Station.” By 1881, tired of being named after a train depot, locals chose Denver, researching post offices nationwide and finding only one other Denver in the country. F&M Hat Company, founded in 1912, became the borough’s largest employer with 835 workers running two shifts by 1939. Today, around 3,800 people call Denver home in this “Mile Wide Town” northeast of Lancaster. The annual Denver Fair, running since 1981, celebrates the community’s agricultural roots each September. From Victorian homes on Main Street to newer construction spreading outward, Denver properties require HVAC systems built to handle Pennsylvania’s demanding climate.
