Featured program: Various! Performer showcase, July 5th at 6pm


May thru July, we will showcase short pieces by performing artists of all sorts in the Ballroom during First Friday Art Walk. Performers will be utilizing the space to test out new material.

The July line-up will feature improvisation jazz trio Apricot Afterthoughts and Myles Bullen present a freestyle rap storytelling piece that engages audience participation, Jackie Reifer performs a comedic monologue called Reifer Madness, Art Moves Dance Ensemble performs Ancestors Dream, The Mysteria by Gregory Hall presents improvisational and classical compositions, & Ballet Africa Mbonda Congo offers a dance and theater piece about the history of Congo. In the self-directed spirit of the art walk, this series allows the audience to come and go. Stop in for a couple acts or stay for all! Admission is free or $10 suggested donation. Join us again on July 5th from 6:00-7:00pm in the Ballroom!

Welcome to MCMA

In 1815, the Maine Charitable Mechanic Association was the fellowship for Portland’s creative community: the blacksmiths, coopers, carpenters, and more.  Today we’re working to connect that history to the modern makers movement.  Our mission is to inspire and enrich the community by promoting ingenuity, creativity, innovation and the diffusion of useful knowledge.

We are the modern mechanics.

Maine Kids Code

Our first season of Maine Kids Code was a huge success and we are now fully enrolled for the next season! Visit and sign up for the...

Since the beginning, MCMA has been the premier club of master craftspeople, entrepreneurs and their apprentices. Our members include Maine’s do-it-yourselfers, community leaders, the ingenious, and the industrious. Together, for over two centuries, we remain committed to supporting the practice of craft and the acquisition of knowledge.

519 Congress Street is Mechanics’ Hall. Built in 1859, it houses a grand ballroom, our members library, and a historic classroom.  Gallery space, commercial space, and meeting areas are available for member activities, ongoing rentals, and special occasions.

MCMA was an integral part of Maine’s story. Started in 1815 as a guild to teach and promote excellence among Portland’s various mechanical and artistic trades, the founders recognized that together their blended efforts could make a difference in their community, and, in their words, “warm the heart and reanimate the smile.” Carpenters, glass workers, sailmakers and other craftspeople, exhibited at the associations’ various fairs, held lectures, participated in parades with trade banners, and socialized at the hall.

The MCMA library remains the oldest non-academic working library in our state, founded in the same year as Maine. Begun as library for apprentices and tradesmen, and still housed in the historic Mechanic’s Hall, its modern goals, collection, and acquisition policy are currently under review to fit the needs of the twenty-first century mechanic.  The library is a wonderful, peaceful, oasis in the heart of the city, where one can come to find (or lose themselves in) a great book.
