Evidential value: the extent to which the physical evidence tells how and when your scheduled monument was made, how it was used and how it has changed over time.
Gwerth fel tystiolaeth: y graddau y mae’r dystiolaeth ffisegol yn dweud wrthym sut a phryd y cafodd eich heneb gofrestredig ei chreu, sut y cafodd ei defnyddio a sut y mae wedi newid dros amser.
