A structural framing system incorporating large wooden members cut from tree trunks and shaped into square or rectangular sections with mortise and tenon joints held together with wooden pegs called trenals (from “tree-nail”). The frame is laterally braced with strategically placed knee braces. Photo from the Observatory, Portland, Maine, 2021. (Baker, 1994)
