The main walk uses one connected architectural reconstruction of the citadel, published by Ministerio de Cultura Perú. Paths, courts and terraces share one scene. Dimensions, present-day visitor routes and surface appearance are approximate; stone joints and mineral grain are illustrative. No photographic textures are used.
