The significance of pillar symbolism, or columns. Interestingly pillars are different than columns, where Pillars are free standing and columns support.

Mysterious pillars are mysterious. Those Freemasons/masons really do enjoy those pillars. Pillars can be pretty much seen on any Freemasonic/masonic building.

Three columns of Masonry — Beauty, Strength and Wisdom. Three orders of architecture (of the five normally presented, two are considered derivative by Masons) – Doric, Ionic, Corinthian. Doric corresponds to Strength, or so I surmise, because the columns are plain and thicker. Corinthian corresponds to Beauty because of its florid capital. Ionic, therefore must corresponds to Wisdom. And the three officers (are they jewels or lights?) correspond to Wisdom (Worshipful Master), Strength (Senior Warden) and Beauty (Junior Warden).
