Attested: AI iter 15 Moriduno; RC Moriduno; TP Ridumo
Where: AI’s mileages fit the Gittisham Roman fort at SY13259930 beside the river Otter. The Hembury hill-fort at ST112031 or Sidmouth, on the coast, are much less likely locations.
Name origin: About -dunum ‘fortified low hill’ see here. It is often argued that *mor- was Celtic for ‘sea’, but the generality of ancient place names derived from PIE *mori- points to inland water – marshes and lakes.
