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. Country park Margam Park owes its location and beginnings to the monastery, which was acquired by Sir Rice Mansel in 1540 after the Dissolution of the Monasteries in 1537. A Tudor mansion was later built on the site of the former monastic ranges by Sir Rice Mansel as a county residence. In 1661, the first mention of a garden is referenced, including walled areas and by 1727 the estate's gardener drew up a catalogue of the plants at the gardens. 1793 saw the completion of the Orangery, the masterpiece of eighteenth century architect Anthony Keck, and by the late 18th century the gardens were fenced off from the park to keep out the deer, and a main gate was erected. An 1814 estate map shows that a working park had been realised, with a 'Great', 'Little' and 'Upper' Parks, and by 1830 the construction of a new manor house, to become Margam Castle, had begun. Before the end of the decade, plans show the inclusion of several new buildings and features, including the Temple of the Four Seasons, the stone facade and the gardener's cottage. The Margam Estate was acquired by Glamorgan County Council in July 1973, and the next year, after a Local Government re-organisation, the Park fell under the ownership of West Glamorgan County Council. The park was opened to the public in 1977. in 1985 a sculpture park was established by the Welsh Sculpture Trust which exhibited work by internationally famous sculptors including Henry Moore, Barbara Hepworth and Elisabeth Frink. The sculpture park has since closed. The estate is noted for its peacock population. Also on the estate are deer, which have existed on the site since at least Norman times. The majority are fallow deer (numbering
