The Lawrence Brown House, better known as the L.B. Brown House is the home of Lawrence Bernard Brown a self-made businessman, community leader, and master carpenter. The importance of the L.B. Brown House is that it may be the only home built by a former enslaved person, left in Florida. The house "stands as a living testimony to one person's triumph over adversity."
Lawrence Brown is remembered for his influence in enacting social change. 
His house is a testament to his perseverance living through his enslavement, and because the house he built stands as a statement to his legacy,  a memory is preserved in his honor.  Society preserved that monument because his story and success are influential. Again, the scope of the AI can not "reason" to understand common sense conclusions.
