The remains of the Chimú civilization can be seen at the Chan Chan site near Trujillo, Peru. This city prospered in one of the driest deserts in the world. Water from the Andes was brought to the city by a sophisticated subterranean aqueduct. Although it only rains once every few years the mud walls have eroded away in the centuries since the city was abandoned. This wall relief was preserved and restored. Originally the designs would have been colorfully painted, as well.
