The CN Tower is getting ready to give the public rare access to areas of the engineering marvel that are normally closed.

Later this month the 553-metre-tall landmark is participating for the first time in Doors Open Toronto, where members of the public get rare access to the city’s architecturally significant buildings and sites.

On Wednesday, members of the media got a preview of the guided tour of the tower, which explores operational and architectural spaces of Canada’s tallest structure that have never before been open to visitors.

CBC News photographer Evan Mitsui was there to check it out.

Members of the media record cellphone videos of the 300-metre shaft running nearly the full height of the tower’s inner pedestal:
