The Ohio State University at Newark

Newark Earthworks Center

The Newark Earthworks Center (NEC) is an interdisciplinary academic center of The Ohio State University that develops projects and research about the American Indian cultures that produced the monumental Midwestern earthen architecture in order to advance understanding of the cultural and scientific achievements of American Indians to the world. The NEC's projects emphasize American Indian knowledge of the earthworks landscape in the Ohio River Valley, from human settlement until the present.

Since 2008, the NEC has successfully initiated strategies to inform Ohio citizens about brilliant ancient Indigenous earthen architecture and contemporary American Indian issues. The center supports tribal governments' self-determination and cultural sovereignty in their essential roles relating to the preservation, interpretation, and stewardship of pre-contact and historic Indigenous places within their ancestral lands. The NEC seeks to develop respectful reciprocal, sustainable relationships between American Indian tribal governments and Ohio State University faculty, staff, and students to identify research and project goals.

We have been fortunate enough to host several tribal governmental visits by the Eastern Shawnee Tribe of Oklahoma, Pokagon Band of Potawatomi, Wyandotte Nation, as well as Native artists and writers, and faculty throughout our history.

The Newark Earthworks: Enduring Monuments, Contested Meanings (edited by Dr. Lindsay Jones and Dr. Richard Shiels, University of Virginia Press, 2016) came from our first-ever symposium where leading scholars of ancient sites turned their expertise to the Newark Earthworks and demonstrates the NEC's commitment to bringing multidisciplinary perspectives to Ohio's narratives.

Book published about the Newark Earthworks!

The Newark Earthworks are a mystery of the ancient world. However, a new book, written and edited by Dr. Lindsay Jones and Dr. Richard Shiels called The Newark Earthworks: Enduring Monuments, Contested Meanings, answers some of the questions surrounding the geometrical mounds of earth that were built nearly two thousand years ago.

Lecture: Lakota's Philosophy of Life: Tuesday October 10, 2017

Guest Lecturer: Guy Jones (Wakuwa La)

11:10 a.m. - 12:30 p.m.
Alford Performing Arts Hall at the John Gilbert Reese Center

Jones, a Hunkpapa Lakota and full-blood member of the Standing Rock Sioux Tribe, carries in his heart a strength that comes from living in today’s diverse society and the spiritual wisdom of his Lakota upbringing. He has unselfishly devoted his life to the sharing of this knowledge in the interest of promoting healing and respect for American Indians. He speaks honestly on such topics as life on the reservation, the shattering effects of governmental policies, environmental issues, the challenges of drug and alcohol abuse and the survival of his culture.

Octagon State Memorial Open House: Monday, July 31 and Sunday, October 8, 2017

The Newark Earthworks Center and Ohio History Connection are sponsoring an Open House at the Octagon State Memorial on Monday, July 31 and October 8, 2017. The grounds of the Octagon State Memorial will be open to the public for strolling and viewing. We encourage everyone to walk the entire earthworks to experience the beauty of this amazing site.

The enigmatic Great Circle and Octagon Earthworks were built 2,000 years ago by the ancestors of contemporary American Indians. They are notable for their precise geometry that provide astronomical alignments with the moon during its 18-year and 219-day cycle that culminates in the Major Lunar Standstill, observed by cultures throughout the world. Their scale is to the land where they reside and is enormous: the Octagon was built with an area of 50 acres. The connecting walkway is the length of a football field, and the Circle has an area of 20 acres. The walls of the earthen enclosures are tall enough to block the view inside, and the walls are curved and smooth.

For more information on the Newark Earthworks' cultural context and history, visit the Ancient Ohio Trail website.

Lunar Alignment at the Octagon Earthworks

You are invited to see the moon rise in alignment with the Octagon Earthworks. Very few people have experienced this event for hundreds of years.

Join us on either of two evenings: Friday, November 27, or Saturday, November 28. Bring your family and friends. You will be the guests of The Ohio State University's Newark Earthworks Center and the Ohio History Connection.

We will see a northern minimum moonrise at this amazing site built by ancestors of American Indians two thousand years ago. Here is what it looked like earlier this fall:

Friday, November 27, 2015 from 6:15 - 7:45 p.m.
Saturday November 28, 2015 from 7:15 - 8:45 p.m.
Open to the public.

125 N. 33rd Street, Newark, OH
Park in the parking lot and gather at the large sign next to the parking lot. Bring a flashlight. If the weather seems to threaten the event, call 740-364-0584 on either of these days for an update.

The moon follows an 18.6 year cycle. The Newark Octagon, built two thousand years ago by ancestors of today’s American Indians, aligns with eight “standstill points” in the cycle of the moon. Those who built the Octagon understood that every month the place on the horizon where the moon first rises moves south for roughly 14 nights and then returns again. Further, the distance it moves between the first and 14th night grows greater every month for 9.3 years and then shrinks again until it is the same distance it had been at the beginning.

These ancient America Indians identified four "standstills" points when the rising moon seemed to stop going in one direction and began going in the other: the northernmost rising of the moon and the southern-most, the northern minimum and the southern minimum. They also observed another four times when the setting moon did the same: the northernmost and southernmost moonset, the northern minimum and southern minimum moonset.

Although the moon arrives at each of these standstill points only once every 18.6 years, it is very close to each of them on several nights. November 27 and 28 are the last dates on which we are likely to see the northern minimum moonrise for the next 18.6 years.

Newark Earthworks Octagon

A rare moon alignment took place at the Newark Earthworks Octagon this fall. To celebrate the occasion, the public was invited to visit and tour the Octagon Earthworks on Sunday, October 11.

The Octagon is only open to the public for general strolling and viewing from sunrise to sunset for four days of the year, and October 11th was the last of those days for 2015.

Eight different moon alignments are built into the Octagon site, some of which will occur later this fall, such as the northern and southern moonrises and moonsets expected to begin on October 17th at approximately 10:05 p.m. These spectacular lunar alignments and the unbelievable precision with which these mounds were built are just two reasons the Newark Earthworks, Fort Ancient Earthworks and earthworks at Hopewell Culture National Historical Park in Chillicothe are being promoted for inscription on the UNESCO World Heritage site list.

This free event is open to anyone excited to learn more about the amazing alignments of the moon and the Octagon, which only occurs about every 18 years. Tour guides from The Ohio State University’s Newark Earthworks Center and the Ohio History Connection will be present to lead guests through the site and explain the lunar alignment phenomenon.

The American Indian site known as the Octagon was built approximately 2000 years ago and is one of the most spectacular surviving remnants of the Newark Earthworks. The octagonal enclosure is large enough to contain four Roman Colosseums and is connected to a perfectly circular enclosure 1,054 feet in diameter. The architecture of the Octagon Earthworks encodes a sophisticated understanding of geometry and astronomy. The Octagon State Memorial is part of the Hopewell Ceremonial Earthworks and is a National Historical landmark.

For more information please contact us at 740.364.9584 or
The Octagon Earthworks is located at 125 N. 33rd Street, Newark, OH.

We hope to see you in Spring 2016 (date to be announced) at our next open house when you can take advantage of this rare opportunity and come walk where generations of American Indians have walked and experience this wonder of the ancient world!
