Adereth El is considered to be the oldest synagogue in New York that is still operating out of its original location. German Jewish immigrants founded the congregation in 1857, and the building was constructed in 1863. To this day, Orthodox Jews attend services on a daily basis. Until his passing in 2013, Rabbi Sidney Kleiman had been the head of the congregation for sixty years - the longest serving rabbi in the country. Not all of the original architecture remains, as the shul had to be renovated twice during the 1900s, but its old world charm is prevalent throughout. The stained glass windows, the wooden seating, and even the prayer books took us back in time.
