Welcome to the Caleb Butler Lodge A.F. & A.M. website. 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.

Our lodge is comprised of good men of all ages, backgrounds and religions. We strive to become better versions of ourselves by working on our character. Our hope is that by improving each other, we can contribute to the betterment of mankind. As Masons, we choose to live by the tenets of Faith, Hope and Charity. If this is of interest to you, please reach out to us. We are always looking for good men to join our ancient and noble fraternity.


Worshipful Stuart K. Young, Master
