menhire

Menhire are single, upright stones that have been erected by humans. They are a type of megalithic monument and are often associated with prehistoric cultures. The term "menhir" is derived from the Breton word for "long stone," reflecting their common occurrence in Brittany, France. Menhire are typically made of hard rock, such as granite or sandstone, and can vary greatly in size, from a few centimeters to over 7 meters in height. They are often found in groups, known as menhirs or alignements, and can be standing alone or in pairs.

The purpose of menhire is not definitively known, but several theories exist. They may have been used as boundary markers, monuments to the dead, or places of ritual and ceremony. Some menhire are decorated with carvings or cup marks, which may have had symbolic or ritual significance. Menhire can be found throughout Europe, with notable concentrations in France, Spain, Portugal, and the United Kingdom. They are often associated with the Neolithic and Bronze Age periods, dating from around 4000 BCE to 1000 BCE.

The study of menhire is a subfield of megalithic archaeology. They provide valuable insights into the beliefs, customs, and technologies of prehistoric societies. Menhire are protected by law in many countries, and efforts are made to preserve and study these ancient monuments. Some menhire are open to the public for visitation and offer a glimpse into the prehistoric past.
