For the visitor the basic purchase is La Bretagne des mégalithes by Pierre-Roland Giot (Rennes, 1997), a masterpiece in the use of colour-coding and other devices to condense a vast amount of information into a limited space. Giot does not attempt completeness in Carnac and the surrounding area, and here Le guide des mégalithes du Morbiham by Gabriel Le Cam (Spézet, 1999) is invaluable. For the interior of this same region, GouezinPhilippe, Les mégalithes du Morbihan intérieur (Rennes, n.d.) has a detailed study of the monuments. Aubrey Burl's Megalithic Brittany (London, 1985), though dealing with only a fraction of the monuments covered by Giot, remains the only guide that tells the reader how to reach each site. The 1:25000 maps of the Institut Géographique National are invaluable as they show the location of many monuments.

Le RouxCharles-Tanguy, Gavrinis (Rennes, 1995). Some 29 orthostats were used in the construction of the passage and chamber, and of these 23 are engraved, most of them over every available space, so that Gavrinis is one of the treasures of prehistoric art. This strongly suggests that the building had a special purpose, perhaps as a mausoleum for a person of outstanding importance.

Most of the passages have been bricked up, presumably for safety reasons. The orientations of graves B, C and D are all close to 133°.
