Two niches on the northwestern wall of the prayer hall are decorated with Biblical scenes. The northern niche has a depiction of trees in a field with hanging musical instruments (Ps. 137); the southern one shows Mount Sinai with the Decalogue staning on its top in raditating beams of light. The vaults of the niches are painted as sky with six-pointed stars. Lists of Siret Jews who perished in Transnistria are situated inthe niches.
