It's a fairly difficult endeavor to reconstruct an Iron Age roundhouse, what with all of the archaeology training required and such. Persons with such interests who lack the necessary training need worry no longer, as the BBC has created a rather fine site that lets users take in many facets of archaeology, including the aforementioned roundhouse. The site also includes overviews of various fields of archaeology, complete with first-hand commentaries and photographs. The "Techniques" area includes a feature titled "The Story of Carbon Dating" and a piece on the relationship between archaeology and metal detecting. The site is rounded out by the "Reconstructions" area, where visitors can view that roundhouse and also look into the reconstruction of an Iron Age chariot.
