“The so-called “mausoleum” is actually an open air rotunda with a huge limestone table in the middle. Around the table are thick stone chairs not only representing the members of the McMillin family, but actually containing their ashes and acting as headstones. This was meant to represent the family dinner table that the McMillins would rather around. There seems to be an empty space at the table and it is said that this was meant to represent the McMillin son who turned away from Methodism. The table is circled by a six Roman columns and a single broken column which is said to represent the unfinished nature of man’s life. The columns were originally going to hold a brass dome over the table, but in the end the family opted to leave the site exposed to the elements. Even the steps leading up to the monument were numbered with Masonic significance to represent the stages of life.
This meaningful and loaded statement on death and family is open to the public”
