The code-breaking machine was the brainchild of mathematician Alan Turing
A charity with royal links is to project-manage restoration at Britain's World War Two code-breaking centre that is now a tourist attraction.
The Prince's Regeneration Trust will oversee the work at Bletchley Park in Buckinghamshire.
Some of the famous huts at Station X will be revamped to show what life was like there during the 1939/45 conflict.
The Heritage Lottery Fund has awarded £465,000 for the work at Bletchley, which attracts 100,000 visitors a year.
The trust will be primarily responsible for appointing and supervising progress of the design team and other consultants.
The charity will also help to obtain the necessary listed building and planning consents and prepare reports for a second round application to the Heritage Lottery Fund for £4.1m.
Trust chief executive Ros Kerslake said: "Our aim is to substantially increase the number of visitors to Bletchley Park by making the centre attractive and relevant to visitors of all ages and backgrounds.
"This is a part of our 20th century history but we want it to be a top 21st Century visitor destination."
