Monument signs generally fall into two categories.
The monument sign can be a place in an existing ground monument in front of a shopping center where space is available. It may have limits as to how much and what can be placed into it for an effective sign and within the centers standards.
This type of sign can also be a total sign package with the actual monument constructed to fit your sign and have about whatever you desire placed on the sign. It optionally provides sophisticated LED messaging and ground lighting options, again depending on your zoning and ordinance limits.
