Cromlechs were constructed during the Neolithic period, between 4,000 and 2,000 BC, and continued to be built into the Bronze Age. The purpose of these monuments is not fully understood, but they are thought to have been used for a variety of purposes, including:
* Astronomical observatories: Some cromlechs are aligned with specific astronomical events, such as the sunrise on the summer solstice. This suggests that they may have been used to track the movement of the sun and other celestial objects.
* Religious ceremonies: Cromlechs may have been used as places of worship or ritual. This is supported by the fact that many of them are located near other prehistoric religious sites, such as burial mounds and henges.
* Burial sites: Some cromlechs are associated with burials. This suggests that they may have been used as funerary monuments, or as places where the remains of the dead were cremated.
The construction of cromlechs required a significant amount of effort and resources. The stones used to build them were often very large, and they had to be transported long distances from their source. This suggests that the people who built these monuments had a high level of social organization and cooperation.
Cromlechs are an important part of our prehistoric heritage. They are a reminder of the complex and sophisticated societies that existed thousands of years ago. They are also a valuable source of information about the beliefs and practices of our ancestors.
