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.
