A turren is a type of ancient structure, often resembling a tower or a mound, typically found in archaeological sites. These formations are usually associated with prehistoric or ancient civilizations and can serve various purposes, including defense, religious practices, or as burial sites. Turrens can vary in size and shape, depending on the culture and region in which they were built. They are often made from local materials like stone or earth and can provide valuable insights into the social and cultural practices of the people who constructed them.
