Hagworm Hill and Seamer Beacon are Bronze Age Tumuli but their origin is way before that. They are both from the Ice Age and are deposits of morainic material left by the North Sea Ice Sheet.

Seamer Beacon has an excellent aspect (being located on high ground above Scarborough) and is perfectly placed to relay signals from Scarborough Castle to the hinterlands of the vale of Pickering and beyond.

There was once a Roman signal station (not to mention Bronze and Iron age settlements) situated on the Scarborough Castle site and given the local barrows and earthworks, it it safe to assume that this site has been utilised since the Bronze Age.

The position of this site has not been lost on the telecommunications world, there is a large array of dishes and masts situated close to the site. Continuity of use through the ages.....

The Oxford English Dictionary says a hagworm is "A northern name for the adder or viper; but in some districts applied to the common snake, and in others to the blindworm" (the latter being the slowworm).

Bowl barrows, the most numerous form of round barrow, are funerary monuments dating from the Late Neolithic period to the Late Bronze Age, with most examples belonging to the period 2400-1500 BC. They were constructed as earthen or rubble mounds, sometimes ditched, which covered single or multiple burials.
