The present invention is directed to a Pre-cast Decorative Retaining Wall consisting of concrete walls constructed on a horizontal surface normally at a manufacturing facility, on rolling platforms, or preferably built on the construction site where after curing to 3000 psi the pre-fabricated walls can be shipped to and installed at a building site. In the flat state the panels can have a wide variety of decorative elements readily applied to both the upper and lower downside reflection surface. A unique feature is the buttress system that is added to the back of the wall system when elevated retention is required. By pouring the buttress portion on top of the footing pier or caisson, and tying into the pre-decorated wall with reinforcement, an eco-friendly, design optional retaining wall system is accomplished which can be rapidly and safely installed.
