Two families of monuments
As elsewhere in Europe, Armorican megaliths belong to 2 distinct architectural families:
- "Spatially defined structures", where the monument is concealed within an outer shell. This is the largest family of "megalithic mausoleums", consisting of cairns, mounds and tumuli, and containing various types of tombs, some of which were accessible and some sealed in by the outer structure.
- "Dispersed" structures, consisting of single stone blocks, standing either in isolation or in loosely spaced groups. All the stones are significant both by themselves and in relation to the surrounding landscape.
