Brompton Lines is a linear earthwork situated in Kent, consisting of a substantial bank and ditch that runs across the landscape. The monument dates to the Iron Age and represents a defensive or territorial boundary feature characteristic of that period. The earthwork's precise function—whether primarily defensive, administrative, or ceremonial—reflects the broader patterns of land division and control evident in Iron Age Kent. As a scheduled ancient monument, Brompton Lines contributes to understanding the development of settlement patterns and territorial organisation in south-eastern England during the prehistoric period.
