Ventarron is an early ceremonial mound in the Lambayeque Valley of northern Peru, with a base construction phase radiocarbon-dated to approximately 2000 BCE — placing it among the oldest temples on the north coast. The structure was built of stacked river cobbles bonded with clay mortar and faced with painted plaster. Walter Alva, who is best known for the 1987 discovery of the Lord of Sipan, directed the excavations that exposed the temple beginning in 2007. The most striking find was a polychrome mural in red, white, black, and yellow depicting a deer ensnared in a net — the oldest known mural painting in the Americas. In November 2017 a brushfire swept across the site and severely damaged the mural and surrounding mudbrick architecture, prompting an emergency conservation campaign and partial restoration.
The early date pushes the regional temple-building tradition back to a period long thought to be aceramic on this stretch of coast.
