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 1,000 antique and vintage bottles from 1900-1971 and the 1780 Maria Theresa Thaler coin (pictured). See our Facebook page for photos of our finds!
Since Springs 2025, we have added 12 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 nonprofit 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.

(Ages 5-19, multiple class times available each week)

archaeology Garden Project - 1830 Early Settlers
When European settlers arrived in Berrien County, there were no stores - nothing. Everything they ate had to be grown or hunted. Through hard work, they thrived. In this class you will recreate an early settler garden complete with foods they ate in a real-world project. (Ages 6-20)
Ancient Garden project - 1000 Years ago in michigan
Recreate a 1000-year-old Native American garden from the Woodland period based on Michigan's very own archaeology record. The Woodland people (3,000 - 1,000 years ago) were large scale farmers. (Ages 8-20)

Students can also submit their photos to a special youth photo archive for future generations to enjoy. (Ages 8 - 20, multiple class times available each week)
Historic Court Trials
Bring your acting skills and reenact some historic trials and learn about justice in the 1800s. The History Center has generously allowed us to use the historic 1839 Courthouse in Berrien Springs for this class - Michigan's oldest surviving courthouse! (Ages 10 - 20)

(Ages 8-20, multiple class times available each week)
Genealogy 101

He followed his own family's line back to the 800's and discovered he was a direct descendant of the Viking King, Olaf the Holy. (Ages 8-20, multiple class times available each week)
Historic Tree Rescue - 250 Year-old oak

We will learn how to preserve old historic trees, restore Lucius to his former glory, and liberate an old apple orchard next to him. (Ages 6-19)
1000 Bottles Project
Got a Tarragindi Bottle?
We have found over 1000 intact antique and vintage bottles from 1900-1971 at the Tarragindi dig. Bottles tell a story, so what are we doing with them?
We are creating an archive of each type of bottle we find. This tells us what products people used or liked during that period. We also let our students keep bottles we have multiples of so they can discover the bottle's story. Can they can identify how old it is, what product was in it, and if the company or product is still around. If not, what happened? We give some to local libraries, churches, and schools for their programming. We also donate them to local nonprofits to use to raise funds for their programs and let their patrons know about ours. Nonprofits are stronger when we work together. Thank you for your purchase and support of local nonprofits if that is how you found out about the Tarragindi Initiative. We have also created a special memorial with some of the significant number of alcohol bottles found from the same period. The property owner from that time was just 18 when he was sent to World War II. We use these bottles to help students pause and ask, “What happened to you?” It’s a way to explain what PTSD is, how to recognize it with compassion, and how to support those healing from PTSD and Adverse Childhood Experiences — especially children.
Summer 2026 Old Jailhouse Dig
Big Finds at our Summer Dig!
This summer, Dr Jan Sigvartsen PhD and over 100 community members continued their search for the lost 1838 Berrien County "Old Jailhouse" behind Michigan's oldest courthouse. The most significant finds included an 1804-1807 "Drapped Bust" United States quarter coin, and a black, fossilized deer rib bone. Several "dud" arrowheads were also found along with a large number of chert shards that suggested arrowhead making took place on this site in the past. A large uneven hardened clay pan with charcoal and chert shards embedded into it was discovered in both squares at 35cm in Square 1 and 31cm in Square 2.
An amateur dig in 1975 failed to locate the 1838 Jailhouse. An 1860 map of Berrien Springs showed that the Old Jailhouse orientation was different to what was expected by the 1975 dig team and resulted in them digging in the wrong location. The 1975 amateur dig was also searching for a running foundation, or a basement, and may not have considered an alternative foundation structure. One of the sides of Square 1 in the 2026 dig by Dr Sigvartsen and his team revealed a deposit of gravel, suggesting it may be disturbed gravel backfill on a pole structure building. It is possible that the 1838 Jail was a pole structure, much like a barn. As such, it could have been completed in a matter of weeks, given buildings at the time did not have plumbing, electricity, insulation, or installed kitchens and bathrooms.
The 1838 Old Jailhouse was moved in the 1870s to the corner of Main and Ferry Streets to become the rear of Kephart's Pharmacy, which was later torn down and a brick building built in its place. The Old Jailhouse was then moved to another location and used as a house until the 1960s when it was demolished. A photo of the Kephart pharmacy exists (see insert photo), and if new siding was not put on the Old Jailhouse, it appears it may have resembled the Courthouse. A dig at this site will continue in the Fall 2026 semester and will look for similar gravel deposits to confirm if the building was indeed a pole structure.
Dr Sigvartsen would like to thank the Berrien Community Foundation and Tarragindi Initiative donors who made this dig possible. You can look at some of our finds on our Facebook page.

Breaking News
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.
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.
Tarragindi Team raises funds for gardens at Old Courthouse Square
This semester, the Tarragindi Team raised funds to replant and mulch the gardens at the Historic Courthouse Square in Berrien Springs, Michigan.
Members of the Tarragindi Team also donated their time to weed, plant, and mulch. Local residents also donated plants, including Mrs Virgina Clark, who at 95, is one of Berrien County's oldest residents. A retired schoolteacher, her home was formerly the Long Lake Schoolhouse, built in the mid 1800s and one of Berrien County's first schools.
"We just love that Mrs Clark, one of the county's oldest residents, donated plants to another oldest resident of Berrien County - our very own 1839 Courthouse, Michigan's oldest Courthouse," says Leanne Sigvartsen.
