1911 Encyclopædia Britannica/Herstal

HERSTAL, or Heristal, a town of Belgium, less than 2 m. N. of Liége and practically one of its suburbs. The name is supposed to be derived from Heerstelle, i.e. “Permanent Camp.” The second Pippin was born here, and this mayor of the palace acquired the control of the kingdom of the Franks. His grandson, Pippin the Short, died at Herstal in A.D. 768, and it disputes with Aix la Chapelle the honour of being the birthplace of Charlemagne. It is now a very active centre of iron and steel manufactures. The Belgian national small arms factory and cannon foundry are fixed here. Pop. (1904) 20,114.
