Margam Country Park is a country park estate in Wales, of around 850 acres (3.4 km2). It is situated in Margam, about 2 miles (3 km) from Port Talbot in south Wales. It was once owned by the Mansel Talbot family and is now owned and administered by the local council, Neath Port Talbot County Borough Council. Situated within the park are three notable buildings: Margam Abbey, a Cistercian monastery; Margam Castle, a neo-Gothic country house that was once the seat of the Mansel Talbot family; and the 18th-century Orangery. The park is designated Grade I on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.
