This section through the Purple Garden, Golden Cave, swimming pool, Wantilan and dining pavilion illustrates the relationship of the built-up areas of the swimming pool and Wantilan to the original ground level, indicated by the dark line at the bottom. From the pool on the west (left) side, the Wantilan appears to be a single-story building, while the east (right) side drops away to the dining pavilion below. The Golden Cave, with its waterfall facing the Purple Garden, is also illustrated here.
