Such communication, I believe, already existed before the _Notitia_ system was set up. The Peddar’s Way, “one of the best preserved Roman roads in East Anglia,”[27] can be traced to-day for 45 miles from the borders of Suffolk (starting no doubt from Colchester) to Holme-on-Sea, at the eastern headland of the Wash. This spot is four miles west of Brancaster, the northernmost fort on the Saxon Shore, and the presumption therefore is that it was laid down before that fort was built. Pointing from the opposite promontory of the Wash (which would have to be crossed by a boat journey of perhaps ten miles) an undoubted Roman road passes by Burgh into the Wolds, and communicates directly through Caistor with the Humber, and by branch-ways with Lincoln and York. The town of Wainfleet (All Saints), some six miles west of this promontory, is often said to have been the Roman haven for the Lindsey coast; but it is singularly poor in Roman remains, and its supposed name of “Vainona” is an invention of the eighteenth century. The road just mentioned is difficult to follow in the Marsh east of Burgh, but there are signs of it outside the Roman Bank west and south of Skegness. Here, according to tradition related by Leland, stood a walled haven town “with a castle,” which was destroyed by the sea not long before his time; and the shifting sandbanks of “The Knock” now covering it must have been the promontory which gave to Skegness its name. Mediæval documents mention _the site_ of this “castle,” but are silent as to its owner; we may therefore infer that it was the ruins of a Roman _castellum_, which in other instances, both in our county and elsewhere, is called a “castle.” Such a conjecture is incapable of absolute proof; but as Peddar’s Way ends in no walled fort, there would naturally be one on the opposite coast. The coincidence is at least curious that the two _Notitia_ forts of Branodunum (Brancaster) and Præsidium (which has been placed in our county) were both garrisoned by a body of Dalmatian cavalry, whose native shores were marshy tracts indented by deep bays.
