Street in Switzerland

This is a picture of a town with a clock tower and a route through the bottom of the tower to the town on the other side. I feel sure I should know where this photo was taken, in fact I'm pretty sure I've already posted a similar photo here on found-film, but I can't find it. Perhaps someone who views this picture can tell me?

The date is 1971 which was written on the slide box the image came from.
