Huaca El Dragon, also called Huaca Arco Iris, is one of the easier Chimu archaeological sites to visit around Trujillo. Its adobe walls and relief decoration give a more intimate view of north-coast pre-Inca culture than the vastness of Chan Chan alone.
The site is best understood as part of the wider Chan Chan landscape. Visit with sun protection and a guide or good notes if possible, because the meaning of the reliefs and sacred architecture is not obvious at first glance.
