Overview

  • Utility workers installing an underground gas line for Cálidda in Puente Piedra uncovered a pre-Hispanic burial two meters from a residential gate on July 31.
  • The interment, attributed to the Chancay culture dating to around 1,000–1,200 years ago, contained a seated individual wrapped in burial cloths.
  • Excavation teams retrieved four clay vessels and three pumpkin shell artifacts that bear the black, white and red iconography of the coastal fishing-based civilization.
  • Cálidda has recorded more than 2,200 archaeological finds during two decades of network expansions across Lima’s 400-plus huacas sites.
  • Peru’s mandated archaeological monitoring in urban infrastructure projects ensures continued discovery and preservation of the capital’s buried pre-Inca heritage.
