South Clettraval is a remarkable archaeological site featuring chambered cairns, a standing stone, and an aisled house. The chambered cairns are ancient burial monuments, typically dating back to the Neolithic period, characterized by a central chamber surrounded by a circular mound of stones. The standing stone, often referred to as a menhir, is a tall, solitary monolith likely used for ceremonial or ritual purposes. The aisled house, a type of ancient dwelling, consists of a rectangular structure with two parallel rows of stones supporting the roof, creating a central aisle. This unique combination of ancient structures offers a fascinating glimpse into the lives and practices of prehistoric communities.
