About & History of the Lalumondiere

Along the Big River in Jefferson County, not far from St. Louis, sits a secret delight.  Traveling across the bridge, in the town of Byrnesville, your eye is drawn upriver to a scenic dam & waterfall where you catch a glimpse of flowers hanging from a 3 story structure presiding over the rivers' edge.  You have discovered the historic Byrnesville Mill. 

As you wend you way through the open breezeway, you feel your senses awaken to the sound of rolling and tumbling water, a perfect backdrop to the sight of multi-level patios, fish ponds, and flower gardens.

Described as intimate, nostalgic, unpretentious, and with eclectic charm, the mill home itself - as well as it's transformation to a one-of-a-kind venue for events & weddings - are some of Jim and Jeannie Lalumondiere's proudest achievements, and reasonably so.

Qualities of love and ingenuity, the belief in preservation and an abiding respect for nature have transformed the Byrnesville Mill into what is today knows as.....The Lalumondiere.


Once a grist mill owned by Patrick Byrne, the Byrnesville mill was the center of commerce for the young town of Byrnesville, Mo. from the mid 1800's and into the 20th century.  The town was also home to a grocer, dance hall, blacksmith, post office and several taverns, but it was the mill that put it on the map and drew farmers and families together.

In 1974 the Lalumondiere's rescued the mill from decades of neglect.  After securing the foundation, they blended their time raising children with the ongoing creation of their beautiful mill home and gardens.

As the years have progressed, their desire to share their special spot with others has brought about the creation of The Lalumondiere....Mill & Rivergardens, an outdoor venue and B&B Homestay site now offered to the public.

It is an opportunity for others to create memories of their own - of weddings and laughter, music and dancing, quiet retreats, family reunions, or corporate meetings away from the boardroom.  This wonderful landscape of opportunity can be shaped to fit your own special needs or desires.
