Nestling in the beautiful Mellte Valley, surrounded by heather covered moors and rich green farmland is the historic parish church of St. Mary, Ystradfellte. Much of the present church was constructed by Cistercian monks, at the end of the 12th Century. The plain Norman chancel, being slightly offset and of simple masonry, is typical of early Cistercian churches. A rood screen was introduced during the 15th century but was destroyed by Cromwellians in 1660. All that remains today are the two doors beside the pulpit through which access was gained to the balcony. The church is always open for visitors.
