Built by the Dhein family in 1885, this stone and log structure had 24-inch-wide fieldstone walls and hand-hewn beams and served farmers and travelers with horses, wagons, and tack. The centennial barn, featuring the Gold Medal Flour sign, served as a transfer station for corn and grains that could be bought, sold, and shipped by rail to different mills. Rockfield’s historic and commercial area was once a center of commerce and resounded with dynamite mining in the nearby limestone quarry. The limestone was then cooked to create cement in the kilns. Other historic sites at this intersection included a dance hall, cannery, two saloons, and Klein’s General Store/Rockfield Post Office.
