The Moche were a mysterious civilization who ruled the northern coast of Peru beginning two thousand years ago. They built huge pyramids made of millions of mud bricks and created an extensive network of aqueducts. They were also pioneers of metal working techniques like gilding and soldering, which enabled them to created extraordinarily intricate jewellery and artifacts. Due to the lack of a written language, little was known about the Moche civilization until the 1980s when archaeologists began uncovering monuments and tombs containing detailed murals, and incredible ceramics that depicted detailed scenes of hunting, fighting, sacrifice, ceremonies, and explicit sexual encounters.
