It never rains...

Chan Chan is the largest mud city in the world. It was once the capital of the Chimu Kingdom in Northern Peru. The Chimus believed that the earth was flat, and so they built Chan Chan at the edge of the sea to make travel to the afterlife easier. The site is made up of a series of temples, only one of which can be visited - Tschudi.
Tschudi is filled with images from the sea - fishing nets, sea otters, pelicans, fish all adorn the mud walls. It is these animals who, the Chimu's believed, will lead the dead to the afterlife.
The palace has only one entrance, and is surrounded by walls of mud that reach 12m in places. The weather in this part of Peru is consistent. Consistently dry. According to our guide it never rains here, except in an El Niño year. During the last El Niño it rained so much, and for so long that parts of the mud were washed away. They expect similar rains next year and are working hard to get the site covered, using scaffold and traditional cane roofs.
