Reality - Teen TV show from 1990's - early 2000's

I'm trying to find the name of a TV show that was on years ago.  It took place in Ireland, I believe.  The story was a house full of kids living together.  Normal teenage stuff, but the kicker was they were not to discuss religion or where they were from. It was a test for them, as they eventually learned their new friends were mixed of Catholic and Protestant, which of course was a big deal.

Does anyone know the name of this show?

Thank you.
