Our Lodge meets

on the 2nd Monday of each month

Master’s Corner

Welcome to the Caleb Butler Lodge A.F. & A.M. web site. Whether you are already a Mason or wondering what Masonry is all about, we hope you will find this web site useful.

Caleb Butler has been in existence for over 150 years and has a great history which you can read about on our lodge history page. The meetings are held on the second Monday of each month, September thru June, at the Masonic Apartments located at 11 Scully Road, Ayer, Massachusetts. We also have many other events throughout the year so check out the calendar page to see what we’re up to.

The Masons are a charitable fraternity, made up of men of good character, 18 years of age or older, regardless of race, religious affiliation or national origin, who process a belief in a supreme being.

We have a vibrant lodge made up of a brotherhood of varied ages who support each other and their families.   We aim to be good neighbors in the community supporting organizations in our area.   We strive to be better men each day holding true to the tenets of our fraternity.   If this sounds of interest to you, please see the “Be a Freemason” website as well as the Grand Lodge of Masons in Massachusetts website.


Worshipful Jonathan Peckham, Master
