Aspero:

Archaeologists in Peru recently uncovered a structure at Áspero that appears to have been used to observe the sky, adding detail to what is known about early scientific practices in the Caral Civilisation.
- It is a late preceramic archaeological site associated with the Norte Chico civilization (also called Caral-Supe civilization), one of the oldest known civilizations in the Americas.
- It is located in Peru on the right bank of the Supe River.
- Once a major fishing centre for the city of Caral, Áspero was inhabited throughout the Late Archaic period from before 3000 BC to approximately 1800 BC.
- It was a major urban center with monumental architecture, including large platform mounds and sunken circular plazas, serving as a hub for trade, agriculture, and religious rituals.
