The Welsh Room is based upon an 18th century non-conformist chapel, known as Pen Rhiw; today it is part of St. Fagen's Museum in Cardiff. A rustic appeal is achieved through a stained concrete floor, meant to evoke the appearance of a pressed earth floor in the original setting. Blue box pews show areas for wealthier congregants, while other student seating is in the form of pews.
A pulpit reminds one of the travelling reverend who would come to the village and stay for awhile in the back apartment, here referenced by an 18th century tall case clock and an oak storage chest. The Lord's Prayer in Welsh is atop the chalkboard.
