Shakespeare's Globe, the London Eye and Tower Bridge will represent Southwark, Lambeth and the City of London in a series of pin badges to mark the 2012 Olympics.
Londoners had from Monday 14 September until Sunday 18 October to cast their vote from a list of nominations to represent each London borough.
Candidates in Southwark included the pink elephant sculpture at Elephant & Castle.
"Here is one way over seven thousand Londoners are already involved in the 2012 Games," says Sebastian Coe, chair of the London 2012 Organising Committee.
"The landmarks chosen by the public for the pin set showcase what Londoners want the world to remember about their borough."
Each landmark lends itself well to being re-created into a metal pin form alongside the London 2012 logo. Designs will be unveiled early next year by London 2012 and London Councils.
SE1 will be depicted on three of the 33 badges. As well as the Lambeth and Southwark pins, the chosen image for the City of London shows Tower Bridge, which although owned by the City Corporation actually sits between the boroughs of Southwark and Tower Hamlets.
