Courtyard house settlement known as Bosullow Trehyllys, 515m north east of Chun Castle

Bosullow Trehyllys is a scheduled monument in Cornwall, a courtyard house settlement preserved half a kilometre north east of Chun Castle. The name suggests a small cluster of dwellings arranged around a shared space, perhaps a place where neighbours passed bread or warnings between walls. Listing protects the ground but does not guarantee entry, so the settlement keeps its shape in law while the chambers remain closed to casual hands. What is certain is that people lived there, marked the earth, and left a pattern worth saving.
