Wade's Causeway is a sinuous, linear structure of human construction located in the North York Moors national park in North Yorkshire, England. Its origins, age, purpose and extent are subject to ongoing research and debate and have not been reliably established: it was excavated in mid-20th century and dated to the Roman period, but 21st century re-interpretations have suggested a possible Neolithic origin. The name may be used to refer specifically to scheduled ancient monument number 1004876, a length of stone course just over 1 mile (1.6 km) long on Wheeldale Moor. It may be also be applied more broadly to include an additional postulated extension of this structure, incorporating ancient monuments numbers 1004108 and 1004104 which extend to the north and south of Wheeldale for up to 25 miles (40 km). The visible course on Wheeldale Moor consists of an embankment of soil, peat, gravel and loose pebbles 0.7 metres (2.3 ft) in height and 4 to 7 metres in width. The gently cambered embankment is capped with un-mortared and loosely abutted flagstones. Its original form is uncertain since it has been subjected to weathering and human damage.
