The Quran mentions of course the Masgids, which are the places where people prostrate themselves in Muhammadan Islam.
It also names the holy places of the Christians and the Jews -

Allah will certainly aid those who aid His (cause); for verily Allah is Full of Strength Exalted in Might (Able to enforce His Will).
