^ It's an English thing. In America we spell it 'center' in most countries that are English in heritage they spell it 'centre'. There's other words that they spell differently, favour, vs favor, colour vs color. Some buildings/places/things in the US spell it that way to be "cool" or different. I actually end up catching myself spelling it that way sometimes, and I even spell theater like theatre. My mom's side of the family is English, so I guess that has something to do with it.
