The National Museum of Wales owns two fine oil paintings of Margam House, viewed from the north and the south, completed sometime around the turn of the 17th century. A closer look reveals a substantial garden pavilion, known as the Banqueting House, at a little distance from the house. Margam’s mansion has been remodelled a number of times, and the Banqueting House too has seen some changes: it was relocated in the 19th century and survives today as the facade of a very imposing cottage.
In the late 18th century industry was booming in the area around Swansea in Wales. Ever more sophisticated machines were powering the various works, and coal was required to fuel the industry. With copper works and coal mines, John Morris was a wealthy man and lived in style at the newly-built Clasemont , a grand classical mansion. The unusual structure he had constructed to house some of his workers was also eye-catching, but within decades it was dismissed as a folly.
