Entrenchment on Heydon Hill is a prehistoric defensive earthwork located in Somerset. The monument consists of a substantial linear bank and ditch system characteristic of Iron Age fortification practices, though the precise dating and original function of the site remain subjects of archaeological interpretation. Its position on elevated terrain reflects the strategic considerations typical of Iron Age settlement and territorial control in the South West of England. The earthwork survives as a notable topographical feature within the landscape, preserving evidence of ancient land use and defensive organisation in this region.
