character to the subjects. Overall, the traditional view is that religion was practiced in natural settings in the open air. Gildas mentions "those diabolical idols of my country, which almost surpassed in number those of Egypt, and of which we still see some mouldering away within or without the deserted temples, with stiff and deformed features as was customary". However, several sites interpreted as Iron Age shrines seem to contradict that view, which may derive from Victorian and later Celtic romanticism. Sites such as at Hayling Island, in Hampshire, and the one found during construction work at Heathrow Airport are interpreted as purpose-built shrines. The Hayling Island example was a circular wooden building set within a rectangular precinct and was rebuilt in stone as a Romano-British temple in the 1st century AD to the same plan. The Heathrow temple was a small cella surrounded by a ring of postholes thought to have formed an ambulatory, which is very similar to Romano-Celtic temples found elsewhere in Europe. A rectangular structure at Danebury and a sequence of six-poster structures overlooking calf burials and culminating in a trench-founded rectangular structure at Cadbury Castle, Somerset, have been similarly interpreted. An example at Sigwells, overlooking Cadbury Castle, was associated with metalwork and whole and partial animal burials to its east. However, evidence of an open-air shrine was found at Hallaton, Leicestershire. Here, a collection of objects known as the Hallaton Treasure were buried in a ditch in the early 1st century AD. The only structural evidence was a wooden palisade built in the ditch. Death in Iron Age Great Britain seems to have produced different behaviours in different regions. Cremation was a common method of disposing of the dead, but the chariot burials and other inhumations of the Arras culture of East Yorkshire and the cist burials of Cornwall demonstrate that it was not ubiquitous. In Dorset, the Durotriges seem to have had small inhumation cemeteries, sometimes with high status grave goods. In fact, the general dearth of excavated Iron Age burials makes drawing conclusions difficult. Excarnation has been suggested as a reason for the lack of burial evidence, with the remains of the dead being dispersed either naturally or through human agency. Economy of Iron Age Britain Trade links developed in the Bronze Age and beforehand provided Great Britain with numerous examples of continental craftsmanship. Swords especially were imported, copied and often improved upon
