Praesidium - The Defensive Enclosure

The first mention of this Roman station on the north-east coast of Britain occurs in the Antonine Itinerary of the second century. This work gives us a good idea where the station was located, but unfortunately, nothing has been forthcoming from the area of Bridlington in support of the documentary evidence. The First Itinerary is entitled "from the frontier at the entrenchments all the way to Praetorius, one-hundred and sixty-one thousand paces", and describes the route from Bremenium (High Rochester, Northumberland) north of Hadrian's Wall, to a place somewhere on the northern coast of North Yorkshire.

According to Iter I, the Praetorius station is twenty-five miles from Delgovicia, although it has been argued (by Margary for instance) that the distance listed is in error and should be fifteen miles. If this is the case, then this unidentified station is possibly located somewhere near Wetwang in North Yorkshire, which is thirteen miles from the station named Derventio which has been associated with the fort and settlement at Malton, also in North Yorkshire. The southern terminus of Iter I is probably to be found somewhere in the area of Bridlington, but unfortunately, no concrete evidence has been recovered to support this premise.

The Notitia Dignitatum Entry

Praefectus equitum Dalmatarum, Praesidio

"The prefect of the Dalmatian Horsemen at Praesidium."

(Notitia Dignitatum xl.19; 4th/5th C.)

Another classical reference which mentions this station is the seventh century Notitia Dignitatum, the entry is shown above, which also names the late-fourth century garrison. In this instance the name is listed as Praesidium. There is a similarly-named entry in the seventh century Ravenna Cosmology, wherein is listed Presidium (R&C#173), between the unidentified entries Camulosessa and Brigomono.

The recorded names for Bridlington are all of a military nature:

It is interesting to note that although Bridlington Bay was endowed "with many harbours" in the second century, there are no known physical remains anywhere along the current coastline of north-east Humberside. The most likely explanation for this lack of supporting evidence is probably due to a gradual westward shift in the coastline since Roman times, which would mean that these second-century harbours may now lie miles out to sea. The Roman signal-station at Scarborough north of Flamborough Head is particularly interesting because it shows these same forces at work, whereby the eastern side of this defensive enclosure has been lost to the eroding effects of the North Sea (Oceanus Germanicus), and the structure now stands precariously on the edge of sea-cliffs.

There are a number of Roman signal stations strung out along the North Yorkshire coast at Filey (TA1281), Scarborough (TA0589), Ravenscar (NZ9801) and Goldsborough (NZ8315), also further along the coast at Huntcliff (NZ6821) in Cleveland. Aside from the signal stations to the north of Bridlington and the "many [missing] harbours" to the south, there are two Romano-British villas about seven miles west along the road to Delgovicia, at Rudston (TA0866) almost a mile north of the road, and at Harpham (TA0863) about ½ mile south.
