This barn is almost overgrown with vines of some sort, but looks in good shape otherwise. It is at a farm that just sets there waiting to be torn down. What a shame!
These Gothic-roofed barns (also called a ^rainbow^ roof) often last a long time, particularly when they are built of cmu (concrete masonry units: blocks) like this one, and possibly laminated beams. Other than an ill-fitting door, the only dilapidation I see is the window near the ridge line. Barns with Gothic roofs like this are usually dairy barns, also identified by a row of small to moderate size windows along the side walls, providing light for each stall. Judging by the size of the door I would guess this barn is not that large, so four stalls for milk cows seems about right.
