The largest mosque is being built in Strasbourg, France.

Omissions

• The claim does not specify whether 'largest' refers to prayer capacity, total complex area, or cost — the designation depends on the metric used.
• Multiple sources claim the mosque will be 'Europe's largest', but this superlative is contested and has been claimed for other mosques in the past; no independent official ranking of European mosques by size exists.
• The MEP (Milan Mazurek, Hnutie Republika/ESN) presents this fact without context, in a speech pattern consistent with anti-Islam political messaging, omitting any reference to the mosque's community or cultural functions.
• No primary official source (e.g., French government statistical body or independent architectural survey) definitively ranks this mosque as the single largest in France was located.
