History

When New Castle was incorporated in 1888, its economy was largely based on mining coal that was needed by the silver-mining industry to fire silver smelters. On February 18, 1896, a methane explosion in the Vulcan Mine killed 49 men and started a coal fire that was still burning as of 2020. The Vulcan reopened and suffered additional explosions on December 12, 1913 (killing 37) and November 4, 1918 (killing 3).

There are at least 25 coal fires burning near the town. They are normally confined underground, but in 2002 the Coal Seam Fire destroyed thirty houses in New Castle.

From 2000 – 2014 the population grew 129%, much higher than the average growth in Colorado over the same period (20.8%).
