Some very interesting history on the town of Transcona and the RM of Springfield originated with the Transcona Cordite Plant. You can still see the earthworks outlining the factory buildings and roads that once were here, and of course, the ruins of six cordite magazines. A Transcona bawdyhouse at one time counted cordite workers as customers, and the site may have been, for six months, a Japanese internment camp during WW II.
See the cache description for Cordite Magazine for a detailed history.
