Holiest locales in synagogues, traditionally

ARKS

Think of the sacred cabinets where Torah scrolls are kept, often adorned and placed at the front of the sanctuary.

The clue refers to the "ark" in a synagogue, which is the sacred cabinet where the Torah scrolls are kept—considered the holiest spot in Jewish worship. The plural "ARKS" fits because synagogues worldwide each have their own. "Traditionally" hints at the long-standing religious significance, not just the literal meaning of "ark" as a boat. It’s a straightforward definition with no wordplay, relying on cultural knowledge of Jewish practice.
