Tall pillars or slabs are commonly referred to as "columns" or "monoliths," depending on the context.
-
Columns: These are typically vertical structural elements used in architecture to support roofs or other structures. They can be made from various materials, including stone, concrete, or metal.
-
Monoliths: These are large stone blocks or single pieces of material, often used in monuments or sculptures. Monoliths can also refer to upright stones, such as those found in megalithic structures.
