Etz Chaim (Tree of Life) was founded in 1921 as an English language synagogue rather than a traditional Yiddish language synagogue. It is the only immigrant era European style synagogue remaining in Maine.The congregation purchased a former apartment building and in the summer of 1921 began work to convert it into a synagogue. Although the name of the original architect is unknown, the contractor of the project was Louis Serota, a member of the congregation, who applied for a building permit on July 1, 1921, and according to archival records, was involved in the construction of the synagogue.

Since 2010 Etz Chaim Synagogue has been the home of the Maine Jewish Museum. The synagogue’s principal sanctuary is located on the top floor while the museum occupies much of the entry floor. The museum is dedicated to preserving the original turn-of-the-century, European style orthodox synagogue so that future generations can visit and enjoy. It also is dedicated to being a center for Maine Jewish history, art and culture with a full calendar of museum events.

Congregation Etz Chaim is an inclusive, egalitarian synagogue conducting many of its services in Hebrew and others substantially in English. It welcomes interfaith, multi-cultural and non-traditional individuals and families.
