Located in the town of Smithfield, the Kromberg Barn is a transitional agricultural structure that embodies two distinct periods of barn construction. The timber frame was originally erected circa 1820-1830 as part of the Benjamin Stevens farm, and features hand hewn, two-story gunstock posts, tapered rafters, and sidewall construction. Although oriented with gable end doors and a central aisle under the ridge, features which are hallmarks of a New England style barn, the framing system displays the joinery and construction sequence of the older, English-style side wall system, marking this frame as an example of the transition between the two barn forms that were prevalent on Mine's farms in the first half of the nineteenth century. In the early twentieth century, circa 1923/24, the barn was remodeled and the gable roof was replaced with a much larger gambrel roof. Gambrel roof barns became popular in the waning years of the nineteenth century as farmers in many areas of Maine increasingly specialized in dairy cattle and the larger size of the herd required additional space to store large amounts of hay. At the same time that the roof was altered Charles Kromberg, who obtained the farm in 1911, repositioned the central aisle, and installed new stanchions and a poultry room. The Kromberg Barn was listed in the National Register as an agricultural structure that represents two periods of agricultural history. It is a good example of a multi-function, gambrel roof barn popular during the early twentieth century and it is also an example of the transition between English and New England barn construction in the early nineteenth century.
