This arcade is on the “upper lake” in Böblingen. The area around two lakes in the middle of town was revamped for the “Landesgartenschau” in the late 1990, a horticultural show. When a town is chosen to host the show it is usually done in such a way that the areal can be kept and benefit the inhabitants for years to come. I couldn’t find an explanation for this very tall and very barren – and indeed very vertical – arcade on the lakeside. It provides shade and makes for very nice reflections, though.
For One Word Sunday: vertical.
