Clava cairn

A clava cairn is like a big pile of rocks that was made a really long time ago by people who lived a long time ago in Scotland. The rocks were stacked on top of each other in a special way to make a big circle or shape that people could walk inside of.

The clava cairn was used as a special place for people to do things like remember important events or do special ceremonies. Sometimes the people who made the clava cairn would bury things in the ground like special rocks, bones or even people.

Even though the clava cairn is really old, people today can still go and see them and learn things about the people who made them a long time ago.
