Parque Arqueológico Pisac

This guide to the Intihuatana temple at Parque Arqueologico Pisac near Cusco starts with a wall that turns out not to be a wall at all: a shoulder of bedrock the Inca carved directly into a shrine, wrapping a sun-marking stone in a curved granite temple dressed so precisely it needed no mortar. It follows how the site aligns with the June solstice sunrise over the eastern peaks, and what a historian who studied Inca stonework for decades concluded when he compared this masonry to every other site in the empire. Run your eye along the granite curve and look for the seams, barely wide enough for a coin.
