Abstract
A retaining wall block is provided with a core, pin receiving cavities, and pin holes. The pin receiving cavities and pin holes are arranged on the block symmetrically on the block and substantially outside of block corner segments, thus resulting in a stronger block and permitting optimal alignment of the wall block cores when constructing a retaining wall. Retaining walls made using the block have increased strength.
