Rosemary Lane was an area in London, United Kingdom.
Known as one of the dirtiest alleyways of London's East End, the Blighters took an interest in this area. Operating under Bloody Nora, they knocked down a part of Rosemary Lane's slums to make room for one their three strongholds in the borough.
In 1868, Henry Green pointed Jacob and Evie Frye into the direction of several gang strongholds as a means to weaken the Templar control over London. Together with their gang, the Rooks, the Assassins managed to take control of Rosemary Lane for themselves, weakening the Blighters in the City of London.
