The Monument is Christopher Wren's column in the City of London marking the Great Fire of 1666. In A Room with a View, Evie climbs it and places a disc at the top, revealing that Edward Kenway hid something at St. Paul's Cathedral.
Using the history found at the Kenway Mansion, Evie scales the Monument while a speech goes on at its base. The disc at the top produces an image pointing her to St. Paul's.
Wren considered a statue of Charles II and a phoenix for the top before settling on a gilded orb.
Jacob walks with Evie to the column and teases her about Henry Green, reminding her of their father's rule against letting feelings get in the way of the mission, before heading off on his own business. The memory opens with the three Assassins discussing Starrick's move into omnibuses after his railway holdings.
St. Paul's Cathedral
St. Paul's Cathedral sits on Ludgate Hill, the highest point in the City of London, and has a viewpoint. Evie finds the key to the Shroud of Eden in a secret room in its dome and fights Lucy Thorne for it.
Bank of England
The Bank of England is the City of London's central bank and the target of Sequence 6, A Run on the Bank, where Jacob tracks a Templar robbing its branches. You return to its vault twice more: once for the stolen printing plates and once in The Last Maharaja.
Black Swan Yard
Black Swan Yard is one of Bloody Nora's three Blighter strongholds in the City of London, set beside the river. Capturing it for the Rooks is part of taking the borough.
Cannon Street station
Cannon Street station is a City of London rail stop on the north bank of the Thames. In the Jack the Ripper expansion it is where four of Jack's gang lieutenants gather, and Evie clears them out.
