Chan Chan (which literally translates to "Sun Sun") is the largest Pre-Columbian metropolis of South America. It was built by the Chimu civilization, a vast empire that once stretched more than 1000 kilometers from southern Ecuador all the way down the Peruvian coast. Around the very beginning of the 14h century, they built this 20 square kilometer citadel: then and still the biggest adobe city in the world. Impressive sculptures and wall carvings adorn the entire city. Chan Chan is very easy to reach from Trujillo, and it is well worth a visit. Combis to Chan Chan (1.50 PEN) leave Trujillo every few minutes, and a taxi from Trujillo runs 10 PEN.
