Île Vierge is a 6-hectare islet lying 1.5 kilometres off the north-west coast of Brittany, opposite the village of Lilia. It is in the commune of Plouguerneau, in the département of Finistère. It is the location of the tallest stone lighthouse in Europe, and the tallest "traditional lighthouse" in the world. The International Hydrographic Organization specifies Île Vierge as marking the south-western limit of the English Channel.
