Stonehenge consists of a circular setting of large standing stones, known as sarsens, topped by lintel stones in the center. The outer circle is surrounded by a circular earthwork bank and ditch. There are also avenues of stones leading away from the main structure.

A mass structure is typically made by assembling large numbers of individual elements or components, such as bricks, blocks, or stones, to create a unified whole. These elements are typically arranged in a way that provides stability and load-bearing capacity, and may be held together using mortar, cement, or other binding materials. The design and arrangement of these elements are carefully planned to ensure that the structure can withstand intended loads and environmental conditions.
Stones are small, smooth, and usually used for decoration or construction. Rocks are larger, rougher, and can be made up of multiple minerals.
