Storm reveals history at Louisbourg (Canada)
The storm surge laid open an old defence wall and other structures long thought to have been destroyed, and there are fears another storm could destroy them.
"This was originally built in the 1730s," said archeologist Rebecca Duggan, pointing to a newly exposed wall. "The interesting thing is we thought most of this wall had long eroded."
The fortress was built by France as a defence against the English. Fifty metres of the original French settlement is now exposed, including a house foundation and burial plot.
