'Kéibierg' sounds like cow hill – but probably isn’t.
It is the old name, still used locally, for the stretch of the rue de Trèves roughly between the railway bridge and the Äppelwee. Records say Geyersberg (1506) and Geschberg before any mention of Kuhberg (1714). Historians suspect a distortion: of 'steep hill', or of Geier, vulture – perhaps because the abbey’s gallows stood on today’s Fetschenhof.
