Pre-dating even the pyramids in Egypt, Brazil’s pyramids are considered the oldest in the world, having been built around 3,000 BCE. These ones are a lot more mysterious than their African counterparts, though, with no written records of their construction in existence.
The pyramid near Jaguaruna in Santa Catarina State is one of the last remaining in Brazil. It stands 100 ft tall (though researchers think it may have once been much taller) and has a base covering an impressive 25 acres. However, archaeologists reckon there were once thousands of pyramids built along the Atlantic coast of southern Brazil.
And why along the coast? Well, that’s because these pyramids were made using only seashells. As a result, many have been mistaken for rubbish heaps over the years and destroyed to make way for development.
Brazil’s pyramids were built over the course of decades, or even centuries, and appear to have been used for burials and other religious purposes, just like the ones found in Egypt. However, more like the pyramids found in other parts of the Americas, structures were built on top of them.
