The Roman Map of Britain Duroviguto or Durovigora ? Grandford? Denver?

Durouiguto (R&C 101) next

    Durouiguto appears to be duro- 'fort' and an unidentified second element uiguto. Circumstances suggest that uiguto might be an error for uigora. Ekwall thought Vigora 'the winding river' might be the old name of the Wissey found in Wereham Wigorham 1060. Ekwall points out that the course of the Wissey, and other rivers in the fen districts, have changed considerably over time (see ERN pp 476 and 465-7). If Durovigora 'fortification at the Vigora' is correct, then a site on Margary 25 (the fen road, upton-peterborough-denver) seems likely as far east as Denver. The potential sites east of Peterborough are (1) March, Grandford (TF3999) with a possible fort; (2) March, Flaggrass (TL4398), (3) Upwell (TL4997), and (4) Nordelph (TL5700), (5) Downham West (TL5800), and (6) Denver (TL5900).

Durouiguto has been traditionally assigned to Godmanchester (TL2470). It is connected by direct road to Water Newton.

'It is likely that a fort of the post-Boudiccan period was briefly in garrison at Grandford, north-west of March, but the principal remains are those of salt-making sites and of small farms.'
T W Potter and R P J Jackson The Roman site of Stonea, Cambridgeshire Antiquity LVI 1982 p 111.

   The Roman coastline was significantly inland from the current coast of The Wash. The mouth of the Wissey was likely in the vicinity of Denver.
