The elements that make a building a synagogue are the aron ha-kodesh (holy ark or niche in the eastern wall, containing the Torah scrolls); the amud (prayer desk, facing the ark) and the bima (the pulpit), where the Torah is read.

Designed by Ben Shahn:

The auditorium, designed by Abramovitz, focuses upon two thirty-foot-high Commandment Tablets flanking the highly noted east wall window. The tablets feature the first letter of each commandment in mosaic, followed by the rest of the text in gold leaf. The playful animal-like shapes of the mosaic letters are often seen in artist Ben Shahn's work.

Note the Holy Ark with drawn curtains.
