Prince William re-opened a newly refurbished homeless shelter on Friday which he first visited 22 years ago with his mother Princess Diana.
The Duke of Cambridge was present for the re-opening of The Passage, St Vincent's Centre, in Westminster, which first first opened its doors in 1980.
Throughout it's 36-year-history, the centre has helped over 100,000 people - a figure the Duke described as "astonishing".
William first visited The Passage in 1994 with younger brother Harry when the pair were 12 and 10, alongside their mother the late Princess Diana.
During a speech today, the Prince said the initial visit had left a "deep and lasting" impression on him about the importance of the charity's work.
As a memento, William was presented with a framed photograph of his 1994 visit, where he is pictured alongside his brother and mother.
