At first glance, you might mistake Akapana Pyramid for a small hill. Standing at almost 60 feet tall, the partially excavated pyramid blends in seamlessly with its surroundings. It’s only when you take a close look that you notice the strong stone walls and regular columns which make up the largest structure ever built by the Tiahuanacota culture.

Taking up an area of about 200 square metres, Akapana is a magnificent behemoth to behold. In fact, the only thing greater than its size is perhaps its function, as archaeologists still don’t agree on what the building with used for. There’s a stone drain in the center, which seems to suggest that the pyramid was used for water. But, there are also craniums and other relics of war that paint Akapana as solemn and ceremonial place.
