Rahtz notes (1991, 140-41), is justified since it serves avowedly to develop archaeological practice itself; the physical remains, or shapes in the landscape can be and are restored to their former appearance with the bonus of being better understood, more educational and interesting; such exotic and special sites capture the imagination of the public and the media and raise the profile of archaeology as a whole. There are other sites that could prove equally good examples of morally justifiable long term research archaeology, such as Wharram Percy (for which see Rahtz 1991, 148-57). Progressing from a straightforward excavation in 1950, with the aim of showing that the earthworks represented medieval buildings, the site grew to represent much more in time, space and complexity. Techniques used expanded from excavation to include survey techniques and aerial photography to set the village into a local context. In conclusion, it can be seen that while excavation is destructive, there is a morally justifiable place for research archaeology and non-destructive archaeological techniques: excavation should not be reduced only to rescue circumstances. Research excavation projects, such as Sutton Hoo, have provided many positive aspects to the development of archaeology and knowledge of the past. While excavation should not be undertaken lightly, and non-destructive techniques should be employed in the first place, it is clear that as yet they cannot replace excavation in terms of the amount and types of data provided. Non-destructive techniques such as environmental sampling and resistivity survey have, provided significant complementary data to that which excavation provides and both should be employed.
