A broch is a type of ancient stone structure found primarily in Scotland. These round, tower-like buildings were constructed during the Iron Age, around 100 BC to 200 AD. Brochs are characterized by their thick walls, which often have a hollow interior and may include staircases and chambers. They were likely used for both defensive purposes and as living spaces. The exact function of brochs remains a topic of debate among archaeologists. Some believe they served as status symbols for local leaders, while others suggest they were communal living spaces or storage facilities. Brochs are an important part of Scottish heritage and provide insight into the lives of ancient peoples in the region.
