Trewassa is a small rural settlement in Cornwall, England, typifying the quieter, agricultural side of the county. It sits among rolling fields and hedgerows, with traditional stone-built farmhouses and narrow lanes rather than any urban centre, and carries the familiar Cornish "Tre-" prefix meaning a farm or homestead.
Historically its economy has been based on farming and local trades, and today that rural character remains alongside a few holiday lettings and commuters who travel into larger towns. Socially it tends to be a close-knit, low‑key community where local events and parish life - rather than commercial amenities - shape daily life, and the surrounding landscape is the main draw for visitors and residents alike.
