'Fetschebuer' means the Fetschenhof well.
'Buer' is Luxembourgish for a well or fountain. This one, on the north side of the Äppelwee, takes its name from the Fetschenhof, a farm first mentioned in 1255. City archives record it in 1878 as a well and watering trough, rebuilt that year by one Michel Hamen. In 1925 the city confirmed Fetschebuer as a place name.
