National Historic Landmark -- Martinsburg, West Virginia -- Berkeley County
A grouping of beehive brick kilns dominates the five-acre industrial site of Continental Clay Brick Plant, established in 1917. Beehive kilns were the primary method of producing brick throughout the 19th century and beyond. These were originally coal-fired ovens, later converted to natural gas. Modern bricks are manufactured using a continuous production line method. Continental's beehive kilns are inactive with only a selected few used for drying sand.
