Sipán is a Moche archaeological site in northern Peru that is famous for the tomb of El Señor de Sipán (Lord of Sipán), excavated by Walter Alva. It is considered to be one of the most important archaeological discoveries in the last thirty years, because the main tomb was found intact and undisturbed by thieves. Tombs were found in Sipán's Huaca Rajada, an area near Chiclayo. Many huaca were found showing Moche jewelry, masks, and art.
