Dry stone

Dry stone is a type of construction where stones are held together without any type of mortar or glue. Instead, the stones are carefully stacked so that their shape and weight hold them together and make the structure strong. This way of building has been done for thousands of years, and it is still used today, mainly for walls or small buildings like huts. It can be a great way of building because it looks nice, and most of the time it does not need any extra support or reinforcement.
