Neath Abbey was a Cistercian monastery, located near the present-day town of Neath in southern Wales. It was once the largest abbey in Wales. Substantial ruins can still be seen, and are in the care of Cadw. Tudor historian John Leland called Neath Abbey "the fairest abbey of all Wales." The Abbey enjoyed varying fortunes, even serving as an early copper works after the dissolution. Although situated near an industrial area, the Abbey's location, on the banks of the Tennant Canal, makes it a tranquil and memorable site for the visitor.
