The Cathedral of Learning now features 27 Nationality Rooms, the newest addition being a Welsh-themed classroom that opened Sunday. Touring onlookers got a first glance of the room, which imitates an 18th century Welsh chapel, as those involved with the creation of the room attended a by-invitation-only event in the Heinz Memorial Chapel at 3 p.m. "It was pretty emotional for these people who had worked so hard and suddenly now could see they'd succeeded," said Nationality Rooms Program Director Maxine Bruhns. "The room is a permanent tribute to our heritage," said Williams.
