Perù. Chan Chan.
A sprawling city of adobe in the Moche Valley, just beyond Trujillo, Chan Chan was the capital of the formidable Chimú empire. Begun around A.D. 1300, it is the largest adobe complex of pre-Columbian America. Among the nine royal palaces, the partially restored Tschudi Palace has unusual friezes and is evocative enough to spur thoughts of the unequaled size and sophistication of this compound of the Chimú kingdom, which reached its apogee in the 15th century before succumbing to the Incas. Chan Chan includes three other sites, all quite spread out, including a modern museum.
