Starlight Castle is a folly on the grand Seaton Delaval estate close to the Northumberland coast. Today only a small section of wall survives, and historic photographs and postcards show it already in ruins a century ago. It was probably built by Sir Francis Delaval (1727-1771) in the middle of the 18th century. The story goes that Delaval wagered he could build a castle overnight, and this was the result.
The Ruined Castle in the grounds of Hagley Hall, near Stourbridge in Worcestershire, was built by Sir Thomas Lyttleton (1685-1751) in 1747-48 as a feature to be visited, and seen as a prospect, on a walk around his park. His eldest son, George Lyttelton (1709-1773), was probably a driving influence, and together they created one of the most perfect sham ruins in Britain.
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.
