A mold assembly is used for manufacturing a ventilated building block. The ventilated building blocks are configured such that adjacent stacked blocks are inverted and reversed, thereby establishing front-to-back air passages that do not provide a sight line and prevent rain from passing through while enabling air ventilation.
