With Napoleon's success at the Battle of Marengo (1800), Alessandria fell to France and became the capital of the Napoleonic Département of Marengo. During this period another substantial fort was built to the north of the city containing impressive and substantial barracks which are still used as a military headquarters and stores (2006). The remains of a second fort to the south of the city (Cristo quarter) have been sliced in two by a railway (Forte ferrovia); a third one still remains in the middle of the same quarter (Forte Acqui).
