Archaeological excavations carried out at the Esplanade powder magazine in Quebec City have revealed the remains of three successive lighting conductor systems. These 19th-century remains are closely examined in the light of contemporary literature and compared with the military instructions concerning the subject. Their presence highlights the efforts made by military engineers of the time to safeguard contents, buildings, and people from the hazards inherent to the storage of explosive materials in powder magazines.
