Description

Fort Beauséjour — Fort Cumberland National Historic Site of Canada is a star-shaped late 18th- and early 19th-century military fortification situated on the narrow neck of land between Nova Scotia and New Brunswick at the southwestern end of the Cumberland Ridge near Aulac, New Brunswick. The designation refers to the site of the fortification as well as Butte à Roger (a French observation post just east of the fortress area), Ile de la Vallière (Tonge's Island), Chipoudy Point, the site of a French redoubt at the river crossing at Pointe de Bute (Pont à Buot), and Inverma Farm (to the north on the Cumberland Ridge).

Heritage value

Fort Beauséjour — Fort Cumberland was designated a national historic site of Canada because:

  • of the roles it played in two major 18th-century conflicts, the Anglo-French rivalry of 1749-63 and the American Revolution of 1776-83,
  • known as Beauséjour, the fort defended French interests in the Chignecto isthmus from 1751 until it was captured by a force of British and New Englanders during a siege in 1755,
  • known later as Fort Cumberland, the post with its British defenders repulsed an attack from sympathizers associated with the American Revolution in 1776, which contributed to keeping Nova Scotia out of the revolution.

The heritage value of Fort Beauséjour — Fort Cumberland National Historic Site of Canada lies in its historical role as illustrated by the extensive cultural landscape encompassing both the fortress and its defensive works, as well as five outlying properties associated with it (Butte à Roger, Ile de la Vallière, Chipoudy Point, the redoubt at Pont à Buot, Inverma Farm). Construction of Fort Beauséjour was begun in 1751 by the French and completed by the British after they captured it in 1755 and renamed it Fort Cumberland. The fort closed in 1835. Parks Canada now administers Fort Beauséjour — Fort Cumberland as a national historic site of Canada open to the public.
