Dig into Berrien County's History

Tarragindi Archaeology Dig

Welcome to tarragindi

Dig up the fun!

In Spring 2025, the Tarragindi Archaeological Dig team and our students (aged 5-18) started excavating an almost 200-year-old farm belonging to one of Berrien County's earliest settler families.  The dig uncovered a slew of items, including over 500 antique and vintage bottles and the 1780 Maria Theresa Thaler coin (pictured).  See our Facebook page for photos of our finds!

Since then, we have added a number of archaeology digs, local history, and genealogy programs that kids and adults can join that are a part of the Tarragindi Initiative.  The Tarragindi Initiative is a 501 (c) (3) organization that wants to see people in Berrien County thrive.  We use local history, archaeology, and genealogy programming as a catalyst to build connection, good mental health, belonging, and a sense of place in Berrien County.  Research shows these are key elements in academic and personal success, maintaining good mental health, overcoming trauma, community engagement, building thriving communities, and encouraging economic growth in the future.

All programs are directed by archaeologist Dr Jan Sigvartsen PhD, who exceeds the Secretary of the Interior's Professional Qualifications Standards for Archaeology as stipulated in the Code of Federal Regulations, 36 CFR Part 61, lives in Berrien County, and is a popular educator and member of our community.

Tarragindi purchases new chairs for 1839 Courthouse

The Tarragindi Team recently raised the funds for the Berrien County Historical Association to purchase period appropriate chairs for the 1839 Courthouse, Michigan's oldest Courthouse.

"The former modern conference chairs looked a little odd in Michigan's Oldest Courthouse," says Dr Jan Sigvartsen, Archaeological Director.  "The 1839 Courtroom is an extraordinary space that we use for some of our programs, so it made sense for us to help bring this beautiful old courtroom back to the 1800s."  The Tarragindi team also donated their time to rearrange the courtroom back into an 1800s courtroom... and open up 30 boxed, brand new, period chairs.

Tarragindi wins Funding

A big thank you to the Berrien Community Foundation for their contribution to our 1838 Old Jailhouse Summer Archaeology Dig program.

"We were thrilled to receive this grant," says Dr Jan Sigvartsen, Archaeological Director.  "Our programming is not just digging in the dirt and learning a few dates.  It blows people's minds when they realize that people have been living in this region for over 12,000 years.  These ancient and early settler peoples' lives, and the ingenious inventions and lifestyles they built in what is now Berrien County, needs to be celebrated and known," says Dr Sigvartsen.  "If they can thrive in this place, modern people can too.

New after school programs

In the Fall 2026 semester, the Tarragindi team will be adding a number of new programs.

These will include our archaeology digs, genealogy 101, historic ancient tools, historic gardening, the Archaeology plus restoration project, historic photography, historic court trials, historic writing, and historic storytelling. 

These programs are all designed to use our local history and archaeology as a catalyst to build a sense of belonging and place among young people and their parents.  Belonging can have a powerful effect on learning, success, recovery from trauma, and mental health in young and older people.
