At my sixth form, there's about 8 blocks/separate buildings. One of them is the RS/dining block, you can call it whatever you like. In one of the rooms upstairs, almost all of the Muslim students in the school come to pray Dhuhr during the lunch break. You even have the little Year 7's who don't usually wear a Hijab, but they take time out, to make wudhu and carry a Hijab in their bag, which i find really cute.
