Roscoff is a commune in the Finistère département of Brittany in northwestern France. Roscoff is renowned for its picturesque architecture, labelled petite cité de caractère de Bretagne since 2009. Roscoff is also a traditional departure point for Onion Johnnies. After lobbying by local economic leaders headed by Alexis Gourvennec, the French government agreed in 1968 to provide a deep-water port at Roscoff.
