Prince William, the Duchess of Cambridge and Prince Harry visited the South Bank on Monday as part of their 'Heads Together' campaign to reduce the stigma around mental health problems.
The Royal trio have set up Heads Together to raise awareness of mental health issues and encourage people to seek help when they need it.
The Royal party spent 90 minutes on the South Bank for the visit which took place on World Mental Health Day.
The visitors were greeted by Rosi Prescott, deputy lieutenant for Lambeth, and David Sharpe of Merlin Entertainments, owners of the London Eye.
In July the Duke and Duchess of Cambridge visited the Southwark-based YoungMinds charity as part of the Heads Together initiative.
