One type of megalith is the single standing stone or menhir.
Some of these are thought to have an astronomical function as a marker or foresight, and, in some areas, long and complex alignments of such stones exist, for example, at Carnac in Brittany.
A menhir (French, from Middle Breton : men, stone + hir, long) is a large upright standing stone. Menhirs may be found singly as monoliths, or as part of a group of similar stones. Their size can vary considerably; but their shape is generally uneven and squared, often tapering towards the top. Menhirs are widely distributed across Europe, Africa and Asia, but are most numerous in Western Europe; in particular in Ireland, Great Britain and Brittany. There are about 50,000 megaliths in these areas, while in northwest France alone there are 1,200 menhirs. They originate from many different periods across pre-history, and were erected as part of a larger Megalithic culture that flourished in Europe and beyond.
