Barkerville before and after the fire

For July 1 celebrations, the National Archives of the UK uploaded several hundred photos of Canada to Flickr, including pictures of Barkerville, British Columbia's most famous frontier town.

Once the largest city north of San Francisco and west of Chicago, Barkerville sprang to existence after Billy Barker struck gold in the in the Cariboo, BC's interior, in 1861.

The town was destroyed by a fire on Sept. 16, 1868, but residents quickly rebuilt. See the before and after shots.
