One of the best-preserved late-Gothic city gates in southern Germany, the Bayertor rises 36 metres over the eastern edge of the old town. Built in 1425 by Duke Ludwig the Bearded as part of Landsberg's second ring of fortifications, it carries an elaborate sculptural program — coats of arms, an enormous Crucifixion group, and a Mary-and-Child Virgin in a niche — all carved straight onto the tower face.
Inside is a small free exhibit on the town's medieval defences. Climbing the tower (about 100 steps) gives the best view of the old town's tiled-roof tangle below and the foothills of the Alps to the south on a clear day. Visit at dusk in summer, when the floodlit gate is reflected in the puddles on the cobbles.
