Stone masonry is the craft of building structures using natural stones. This technique involves shaping and placing stones to create walls, buildings, and other architectural features. Stone masons select stones based on their size, shape, and durability, ensuring that they fit together securely. The process of stone masonry can include various methods, such as dry stone construction, where stones are stacked without mortar, or mortar masonry, which uses a binding material to hold the stones together. This ancient practice has been used for thousands of years, contributing to iconic structures like castles and cathedrals.
