This is the "Museo Tumbas Reales de Sipan" which has the treasures of the royal tombs of Sipan. They take away your camera, cell phone and bags as you enter since there are no photos allowed. I wished my guidebook told me that ahead of time. Lambayeque is located 20 minutes north of Chiclayo. The actual Sipan site is 30km south east of Chiclayo.
