Certain aspects of the archaeological wealth of the Champagne area are revealed through the aerial records available at the present time. Densely populated at the beginning of the Gallic period, and noteworthy for its chariot graves, the region has yielded through air photography many sites -some of them exceptional- dating from protohistorical to mediaeval times. A few of these -not all exceptional- are studied here ; they comfort some recent opinions (LAMBOT 1991, 1993b, 1996, 1997) and may suggest new theoretical views on religious-type structures. The vast elongated enclosures of the late Bronze age, and the sanctuaries (usually Romanised) of the end of the Gallic period, are central in this study. Documents so far unpublished are also presented.
