The Phare des Pierres Noires (English: Black Rocks Lighthouse), is a seacoast lighthouse in the Finistère département of France, designed by the engineer Victor Fénoux and constructed between 1867 and 1871; it was inaugurated on 1 May 1872. Situated mostly on the Pointe Saint-Mathieu, it allows ships to pass through the Chenal du Four ("Channel of the Oven") and avoid at night and during stormy weather the hazards of the Chaussée des Pierres Noires ("Black Rocks Pass"). It is part of the commune of Le Conquet and is owned by the French state.
