Plural of arras; decorative tapestries or wall hangings, especially those from the town of Arras in France.
From Old French 'arras,' taking its name from the city of Arras in what is now northern France, famous throughout medieval Europe for its tapestry production. The plural adds the standard '-es' suffix.
Arras tapestries were so famous that their name became generic—like 'kleenex' for tissues—so any fancy European tapestry got called arras even if it didn't come from the actual town of Arras, which shows the power of a brand at the height of the Middle Ages.
