Typical architectural sign uses include directional, point of purchase signage, directories, regulatory signs, and a wide variety of on-premise signs inside multi-tenant buildings. A monument sign is a ground sign with low overall height. A monument is a detached, freestanding sign whose sign surface is attached to a proportionate solid base or structural frame. Also called ground signs or low profile signs, monuments are typically known for their solid base and low-to-the-ground installation. They can be internally or externally illuminated.
