Behind The Wall

When you climb to the end of the tourist area of The Wall, there is a sign to keep out. When you ignore that sign and continue walking on the well-used path of everyone else who ignored the sign, you come to what The Wall was... crumbling rock, overgrown with trees. The soil in the core of The Wall is being taken by farmers along other sections for their crops, and the bricks are slowly returning to the soil themselves.

The tourist areas are being "fixed". The fate of the other sections is unknown. However, it is this side of The Wall that (for me) is the most impressive and memorable.
