Ancient Ceremonial Plaza found in Peru - Sechin Bajo
Archeologists find 5,500-year-old plaza in Peru
From 2008
A view of the ruins of Sechin Bajo, that was built 5,500 years ago, after it was discovered in Casma in this February 2008 file photo. Archeologists involved in the dig said on Monday carbon dating shows it is one of the oldest structures ever found in the Americas. A team of Peruvian and German archeologists uncovered the plaza, which was hidden beneath another piece of architecture at the ruins known as Sechin Bajo, in Casma, 229 miles north of Lima, the capital.
"All of these reviews are actually talking about Cerro Sechin, not Sechin Bajo. Sechin Bajo is an interesting site archaeologically, but not much to visit. Cerro Sechin is one of the great archaeological monuments of Peru. This is where you find the extraordinary carved figures in bas relief representing the sometimes gory results of warfare, including parts of the defeated as well as the impressive full figures of victorious warriors. Cerro Sechin is easy to reach from the highway or by quick cab ride from Casma. There is a small museum and picnic area adjacent to the incomparable ruins"

An Exploration of Ceremonial Architecture at Huaricanga
The Casma–Sechin culture c. 3600 BC – 200 BC of Peru refers to the large concentration of pre-historic ruins in the valleys of the Casma River and its tributary the Sechin River and along the nearby coast of the Pacific Ocean. The ruins include major archaeological sites such as Sechin Bajo, Sechin Alto, Cerro Sechin, Mojeque, Chankillo and Taukachi-Konkan as well as other smaller sites.
A frieze located at Sechin Bajo dated at 3600 BC is the oldest example of monumental architecture discovered thus far in the Americas. This date, if confirmed by additional discoveries, means that the Casma-Sechin culture may have originated as early or earlier than the Caral-Supe civilization, currently considered the oldest civilization of the Americas.

The Thirteen Towers have been interpreted as an astronomical observatory built in the 4th century BC
The Thirteen Towers solar observatory
The regularly-spaced thirteen towers of Chankillo were constructed atop the ridge of a low hill running near north to south, forming a "toothed" horizon with narrow gaps at regular intervals. To the east and west investigators designated two possible observation points. From these vantages, the 300 meter long spread of the towers along the horizon corresponds very closely to the rising and setting positions of the sun over the year, albeit they are not all visible. On the winter solstice, the sun would rise behind the leftmost tower of Chankillo and rise behind each of the towers until it reached the rightmost tower six months later on the summer solstice, marking the passage of time. The Thirteen Towers of Chankillo could be the earliest known observatory in the Americas. Inhabitants of Chankillo would have been able to determine an accurate date, with an error of a day or two, by observing the sunrise or sunset from the correct tower. A contemporary site in Chincha Valley, Peru, of the late Paracas culture, which also marked the solstice, has recently been examined.
The towers had been known to travellers for 200 years but were not determined to be an astronomical site until 2007 by Iván Ghezzi and Clive Ruggles.

'Oldest religious icon in Americas'
Staff god
The fragment of a bowl dated to about 4,000 years ago bears the image of the Staff God, the main deity in the Andes for thousands of years.
The figure was found at a looted cemetery on the coast of Peru, 120 miles north of Lima.
The area appears to have been the ancestral home of pre-Inca civilisation.
