Barn architecture refers to the design and construction of barns, which are agricultural buildings primarily used for storing livestock, tools, and crops. These structures often feature large open spaces, high ceilings, and wide doors to accommodate farm equipment and animals. Traditional barn styles vary by region, influenced by local materials and climate. Common types of barns include the bank barn, which is built into a hillside for easy access, and the red barn, a classic American symbol often painted in bright red. Barns may also incorporate elements like lofts for hay storage and silo structures for grain storage, reflecting their functional design.
