Did you know that there are honeybee hives on the roof of the Four Seasons Centre for the Performing Arts (aka the Opera House for the Canadian Opera Company)? Check out this short video of a 24-hour timelapse of the hives.
And there are also honeybee hives on the roof of the Royal York Hotel, and the roof of the Opera Bastille in Paris! Crazy, huh?
Han says there are 7 hives up there, which translates to about 10,000 bees!
Oh, and they have their own blog.
