The Dolder is Riquewihr's emblem: a tall medieval gate tower at the upper end of the main street. From outside the walls it still reads as a defensive structure; from inside the village it looks almost domestic, with timber framing and a steep roof above the stone base.
It is the best single marker of the old town's scale. Stand below it and you can see how compact Riquewihr is, squeezed between wall, vineyard, and mountain slope. The small museum inside is worth a look if it is open, but the tower earns its keep even from the street.
