"point d'orgue" is the French word for "fermata". It's "a symbol of musical notation indicating that the note should be prolonged beyond its normal duration or note value would indicate" (from Wikipedia).
The French name litteraly means "organ's point", and refers to the fact that a pipe organ can sustain a note for an undefinite length of time.
