Learn Our History

125 Years of legacy & love Intertwined

The Grand Army of the Republic Building, standing proudly as a symbol of Detroit's history, was once a gathering place for Civil War veterans, echoing with tales of valor and camaraderie. Today, Prime Concepts Detroit carries forth this legacy with reverence and love. As keepers of the storied landmark, we envision not just a venue, but a setting where memories are crafted, and love stories unfold. With meticulous care and a deep respect for its heritage, our endeavors are to weave the spirit of the GAR into every aspect of our spaces, ensuring that its legacy of community and unity endures for generations to come.
