Technically awe-inspiring, the Rogers Centre sports stadium opened in 1989 with the world's first fully retractable dome roof and seating for up to 55,000 people. Tours include a brain-scrambling video-wall screening footage of past sporting glories, concerts and events, a sprint through a box suite, a locker-room detour (sans athletes) and a memorabilia museum. A budget seat at a Blue Jays baseball or Argonauts football game is the cheapest way to see the center.
