de Gannes-Cosby House National Historic Site of Canada - Credit: Wikimedia Commons
The de Gannes-Cosby House in the Annapolis Royal Historic District is the oldest wood framed building in Canada. It is also the world's oldest existing building in the Acadian style. It was built in 1708 by Major Louis-Joseph de Gannes de Falaise, a French nobleman and officer stationed at the French colony of Port Royal in what is today the province of Nova Scotia. The house is built on the foundations of an earlier house destroyed during the 1707 Siege of Port Royal. The core house was a simple wattle and daub construction, but has since been covered in wooden shingles and enlarged in the 19th and 20th centuries. It has been designated as a National Historic Site and is part of the Annapolis Royal Historic District. Read more on Wikipedia
