Personal study. A fanum, the small square temple with a surrounding gallery that is characteristic of the Gallo-Roman provinces.
The form derives from pre-Roman Celtic sanctuaries and is found throughout Gaul, the Germanies and Britain, usually as a raised cella enclosed by a covered ambulatory. Almost nothing of these buildings survives above foundation level, so the height of the cella, the pitch of the roof and the treatment of the gallery are restored from the few better preserved examples and from proportional reasoning on the excavated plans. That is where nearly all the interpretive work on a building of this type lies.
