Battersea Bellows is a Blighter stronghold in Lambeth, one of two in the borough. Henry Green points the twins at it, and clearing it out hands the site to the Rooks and loosens Cletus Strain's grip on Lambeth.
The area used to be working-class housing before it turned industrial. Strain bought a slice of it with no regard for the people who lived there and built his stronghold on the land.
This is the Battersea Bellows stronghold memory. Defeating the Blighters inside turns it into a Rook stronghold and counts toward liberating Lambeth.
Strain's hold on Lambeth also runs through the Templar hunts for Martin Church, the Lambeth Bullies and the Fletchers, bounties on Leopold Bacchus, Mildred Graves and Jesse Butler, and the Strain & Boil factory where children are forced to work.
Echostreet Alley
Echostreet Alley is one of Cletus Strain's two Blighter strongholds in Lambeth, built near Waterloo station. Liberating it gives the Rooks another foothold south of the river.
Lambeth Asylum
Lambeth Asylum is a fictional mental hospital in Lambeth, funded by the Templars in 1868 and the setting for some of Syndicate's darkest memories. Jacob kills Dr. Elliotson here, Evie and Clara seek a cure here, and the Jack the Ripper story ends here.
Lambeth Palace
Lambeth Palace is the Archbishop of Canterbury's residence in Lambeth. In 1868 the escaped Templar Martin Church hides here, and his Templar Hunt sends you inside to finish him.
