[1] Congregation Ahavath Achim was founded in Bridgeport in 1904, for the sizable Hungarian Jewish community whose members settled primarily in the city's West End.

The congregation was initially located on Cherry Street, that was destroyed by a fire in 1910 and subsequently rebuilt;[3] then, in 1926, it moved to Hancock Avenue in Bridgeport.

[4] As the immigrants prospered in their new homeland, they decided to build a "magnificent structure [using] the most modern techniques, glorious stained-glass windows, a beautiful Aron Ha-Kodesh, a lovely, traditional bimah, Colonial pillars, a breath-taking landscaping development ... a gorgeous edifice that would evoke for a blessed generation the proud statement: 'This is my synagogue!

Renovations and additions to the synagogue building were made in 1995 in order to accommodate the growth of Hillel Academy, the community’s Jewish day school, which closed its doors in 2010 due to a low enrollment.

In 2017, the congregation sold its Streatfield Road synagogue to a developer who plans to construct a three-story assisted living center on the redeveloped site.
