The Celtic names of hillforts
Location: just north of Norton Fitzwarren, to the west of Taunton, Somerset
OS map reference: ST 197 263
Celtic name: Morionio
Source: Ravenna Cosmography (30) - Morionio
This is a roughly circular univallate hillfort on the summit of a low hill.
The writer’s reasons for associating the name Morionio with Norton Camp are given in Chapter 10 (Roman place-names in southwest England) of the Home menu. The name is a straightforward compound in the hill-letters m and r with an onio ending.
It is not clear whether the name as it appears in Ravenna refers to the hillfort itself, to a Roman post built inside the hillfort once the occupants had been evicted, or to a Roman fort which was built nearby and to which the name of the hillfort was transferred.
