Utility workers in Peru’s capital have discovered two pre-Incan tombs while expanding underground gas networks. One tomb was empty, but the other contained remains about 1,000 years old, along with clay and pumpkin shell vessels. Archaeologist José Aliaga says the vessels’ design links them to the pre-Incan Chancay culture. Lima, a city with over 400 archaeological sites, often reveals such finds during construction projects. The company responsible for the gas network has made over 2,200 discoveries in two decades.
