Crop mark complex, Orsett is a prehistoric and Romano-British settlement site in Essex comprising multiple enclosures and structures visible primarily as crop marks in aerial photography. The site contains evidence of Iron Age and Roman period occupation, including ditched enclosures, trackways, and associated features that have been revealed through systematic aerial reconnaissance. The complex demonstrates patterns of land organisation and settlement typical of the Essex landscape during the later prehistoric and Romano-British periods. The survival of these features as crop marks rather than upstanding remains reflects the agricultural history of the area and the effectiveness of aerial archaeology in revealing subsurface archaeological deposits.
