The Fortress of Louisbourg is a working reconstruction of a French colonial town as it appeared around 1744, one year before the first British siege. About a fifth of the original fortified town has been rebuilt on its 18th-century foundations, populated by costumed interpreters who re-enact the daily life of soldiers, merchants, fishermen, and the occasional nobleman. The effect is less theme park than living archaeology: the interpreters stay in character, the buildings smell of woodsmoke and salt fish, and the bakery produces actual soldier's bread from period recipes.
The site is large — allow at least three hours. The main fortifications give views over the harbour; inside, the Governor's Apartment, the guardhouse barracks, and the merchant quarter each tell a different part of the story. Period-appropriate meals are available at the town's tavern. The visitor centre at the entrance has an excellent historical display covering both the 1745 and 1758 sieges.
The fortress is about 30km southeast of Sydney, at the southern end of Cape Breton Island. Open May to October; National Parks pass required.
