Since we are talking Capone, this house is reputed to be his summer residence in Canada, it is built up around it now but used to have a network of underground escape tunnels.
Various sources have also claimed that Capone visited Kemptville. The website of the Rideau Glen Golf Club makes the claim that according to an un-named "gentleman that has lived in Kemptville for many years," the rotund, scar-faced thug was an avid golfer, who spent summers at a residence on Oxford Street (whose later owners discovered underground tunnels) and may have even put up the money to help the original owners of Rideau Glen build the course. The local folklore states that Big Al was a left-handed golfer, and wanted a course that would favour left-handers, so he helped to build one. The longtime town resident's father told him he remembered seeing Capone "in his 'big black Cadillac' coming to the course to inspect the progress of the construction." Rideau Glen was established in 1929.
