A team of specialists headed by archaeologist Alejandro Chu has informed that structures found in Bandurria may be as old as structures found in Caral, Peru, deemed as the oldest citadel in the Americas. Located north of Lima, near the city of Huacho, the Bandurria archaeological centre has been found to have similar structures as those found in Caral. Among the similarities are a circular plaza made with circular borders, and a ceremonial centre made of clay, all in an asymmetrical style. According to Andina News Agency, the age of these structures may go back as much as 4,500 years.
Caral made headlines in 2001 when researchers carbon-dated material from the city back to 2627 B.C. It is a must-see for archaeology enthusiasts. Even though the ruins in the dusty, wind-swept Supe River Valley don't approximate in majesty the mountains that surround the famed Inca ruins at Machu Picchu, they are an unforgettable sight under the glow of a fiery sunset. Dotted with pyramid temples, sunken plazas, housing complexes and an amphitheater, Caral is one of 20 sites attributed to the ancient Caral-Supe culture that run almost linearly from Peru's central coast inland up the Andes. The ruins changed history when researchers proved that a complex urban centre in the Americas thrived as a contemporary to ancient Mesopotamia and Egypt — 1,500 years earlier than previously believed.
