 The architecture of most Bene Israel synagogues is rarely stylistically pure and hence hard to define or label, although there are examples of buildings built in the 1930s by the Bene Israel communities of Mumbai and Ahmedabad that are pure Art Deco.A few, particularly those built by the Bene Israel Jews in the coastal Konkan Region of Maharashtra during the 19th century, are interesting blendings of colonial influences, vernacular building traditions, and Jewish liturgical requirements.At one time more than a dozen synagogues existed in these small coastal communities where communities of Jews lived, including at Pen, Alibag, Panvel and Mhasala, but today many are closed or marginally operating due to the much dwindled Jewish population.
