Disable back to calendar button

Is there any way I can disable the “Back to Calendar” button on the eventview of an event? On a page with a right sidebar and an event, containing a location map, the back to calendar button is really misaligned.
And since it has only little value in my site anyway, I would like to disable it.

But how do you do that?
