Sacsayhuaman near Cuzco, Peru.

I chose Sacsayhuaman as a ruin that I’ve been to personally, because of the immense amount of craft and care that went into carving the rocks. This site was once thought of to be a fort. The sprawling grass over what once was a massive structure is fascinating. The rocks are carved so perfectly to create a jigsaw puzzle. They’re huge, with one wall rising roughly 8 feet tall. It’s a true testament to the impressive craft of the time. The ruins left today are simple, yet beautiful.
