The apple that the sculptor included in the statue of Alan Turing represents, on the one hand, what the mathematician ate to take his own life, and on the other hand, forbidden love.
The memorial was symbolically placed between the Institute of Science and Technology of the University of Manchester with Sackville Park on one side, and the gay bars of Canal Street on the other, representing both sides of Turing's life.
Every June 23, Alan Turing’s birth date, people bring flowers to his memorial located in Sackville Park, which is next to the gay village.
This statue is made of cast bronze. The bench has a raised text that reads: "Alan Mathison Turing 1912-1954", followed by the phrase: "Founder of computer science". The phrase is written like the code of the Enigma machine.
In 2009, another statue dedicated to Turing was installed in Bletchey Park. It weighs a ton and a half and was built with half a million pieces of 500 million-year-old Welsh slate.
In 2012 various events were held around the world to commemorate the 100th anniversary of Alan Turing’s birth, as well as his great contributions to computer science.
In 2009 a programmer named John Graham-Cumming had the initiative to send the British government a petition to grant forgiveness to Alan Turing for the persecution he suffered due to his homosexuality.
Literature has also paid homage to Turing. There are novels inspired by him such as "The Cambridge Quintet" and "Cryptonomicon", as well as a play titled "Breaking the Code".
On the plaque of Alan Turing's monument there is a sentence by Bertrand Russell: "Mathematics, correctly seen, possess not only the truth, but the supreme beauty, a cold and austere beauty, like that of a sculpture".
