ST. CHARLES COUNTY, Mo. — Through the rolling hills in Defiance sits one of the few vestiges of early American frontier history in St.
Charles County. The Bryan Mill Grove estate is on over 100 acres on Highway F owned by frontiersman Daniel Boone in the early 1800s. It includes a stone barn likely built by Boone and his adopted son, plus a three-story limestone house built in 1840, after Boone's death.
The site is a mile west of the historic Daniel Boone Home that the St. Charles County Parks Department oversees. Bob Brinkmann and his wife, Kim, refurbished Bryan Mill Grove — the barn hadn't been touched in over 200 years — and hosted fundraisers, parties and other social events throughout the 12 years they've owned it.
Now the couple, who live nearby, are ready to let go. It is listed for sale for $8 million through Coldwell Banker. “It’s a little special piece of property,” Bob Brinkmann said.
Daniel Boone and his family were among the first settlers in the area, coming to the region in 1799 via Kentucky after receiving a land grant from the Spanish, several years before the Louisiana Purchase. Giant doors open to a barn that builder Bob Brinkmann remodeled as photographed on Thursday, May 16, 2024, at his Bryan Mill Grove property that he is selling in Defiance. At Bryan Mill Grove, Boone helped adopted son Jonathan Bryan build the barn that operated as a gristmill, which ground grains for flour, as well as the stone house that was built at least in part by sl.
