Triffid Alley, Hampstead


Triffid Alley

TRIFFID ALLEY is a narrow alleyway behind a number of shops in South End Road, Hampstead. The entrance to the alley is in Pond Street where the memorial sign, provided by the South End Green Association, is located. The sign was unveiled by David Ketterer on Sunday, 24 May 2015 in front of a group of well-wishers. The unveiling of the Triffid Alley sign, which is the only known memorial to John Wyndham in the UK, was the culmination of an extended campaign to see the author recognised for his contribution to literature. While his enduring legacy is undoubtedly his works of fiction, which are still in print more than 60 years after their first publication, the naming of TRIFFID ALLEY is a fitting memorial to the man who gave the world ‘Triffids’.

A Triffid Alley Timeline


Warwick Mansions was built at 37 Pond Street, Hampstead; it includes the entrance to an alley which runs behind Nos. 1 to 11 South End Road.



John Wyndham’s The Day of the Triffids was published including the reference to the alley.



David Ketterer re-read The Day of the Triffids for the first time since around 1952 and annotated his 1981 Penguin reprint copy on page 142 with 'South End Green – site of Orwell’s bookshop.'


April 2011

A proposal was submitted to English Heritage for the erection of a Blue Plaque at the Penn Club, Bedford Place to commemorate John Wyndham’s work. He lived at the club from 1939 to 1963 and it was there that he wrote many of his major works.


Nov 2011

English Heritage rejected the proposal for a Blue Plaque as: ‘The enduring success of Wyndham’s fiction was acknowledged, but it was felt that the Penn Club was not a suitable address at which to site a plaque, given the large number of individuals who have been associated with the club.’ This was the third time English Heritage had knocked back the proposal that John Wyndham should be recognised by the installation of a Blue Plaque.
