Thanks for stopping by my place, the following will answer your question:
The Memorial Wall is made up of two black granite walls 246 feet 9 inches (75 meters) long, designed by Maya Ying Lin. The walls are sunk into the ground, with the earth behind them. At the highest tip (the apex where they meet), they are 10.1 feet (3 m) high, and they taper to a height of eight inches (20cm) at their extremities. Granite for the wall came from Bangalore, India and was deliberately chosen because of its reflective quality.
