I tested a real fragment of Machu Picchu Citadel in Minecraft Java 1.21.4 and imported it through HMCL.

This playable world includes the citadel, terraces, steep mountain paths, stone structures and surrounding terrain. It is generated from OpenStreetMap-derived geographic data with MapMC, then verified in the game. It is an editable approximation, not a hand-built 1:1 replica.

Screenshots are captured inside the imported world.
