I though cancho roano could have a moat like Hanging Gardens have:
See a simulation for cancho roano: all archeologist reconstrutions include the moat and the water

a) Change any wall color. Archeologists found traces of red Paint on the walls. It would enhance the importance of that building.
b)Include the Deep moat filled with wáter that surrounds the building.
Some pictures:
