CentOS7 repository- is there such a thing?

I have found a CentOS7 EPEL repository here: http://www.mirrorservice.org/sites/download.fedora.redhat.com/pub/epel/7/x86_64/ but I was wondering if there is such a thing as just a Centos7 repository (i.e. not the EPEL one)? The reason I ask is I'm looking through a cobbler servers listed repositories, and for the previous version of Centos (6.5) it states it holds both a "Centos6.5-EPEL" repository AND a "CentOS 6.5" repository. Yet when I google to try and find the location a purely Centos repository, I can't find anything.
