The name Herstal is of Franconian origin, consisting of the elements hari ("army") and stal ("resting place", compare "stable"). The first mention of Herstal is in Latin documents from ±718 (Cheristalius corrected to Charistalius) and 723 (Harastallius). The first possibly non-Latinized occurrences are Eristail (in 919) and Harstail (1197).[2]
