Thirty-seven years in the making, the 100 million pound ($160 million) national football centre at Burton-upon-Trent in central England will be the permanent home for all 24 of England's senior and junior teams as well as a training base for aspiring coaches.
France and Spain became world champions a decade after building their national academies and England, whose only major trophy was won at the 1966 World Cup on home soil, is targeting the same result.
"Coming here and seeing these wonderful facilities gives the same feeling as when I first went to the Olympic Park," said Prince William, who chatted with players and tried out the centre's state-of-the-art facilities on a guided tour with Kate.
"It gives me great pride we have created in this country facilities that are beyond compare anywhere else."
Facilities were developed after extensive research into similar centres around the world, including Clairefontaine — the world-famous headquarters of French football — Spain's Cuidad del Futbol near Madrid, the Aspire Academy in Qatar and the Australian Institute of Sport.
One of the 11 outside pitches on the 330-acre site is a replica of that used at Wembley Stadium, where England plays its home matches, with exactly the same mix of grass and artificial fibers. There is also a full-size indoor artificial surface, an indoor 60-meter sprint track, reflex machines for goalkeepers, a high-wire course and a suite of rehabilitation and sports science areas.
The idea for the centre was first mooted in 1975 — finally, it has finally come to fruition.
"I'm rather hoping that the amount of great work being put in here will take us to that elusive World Cup," England manager Roy Hodgson said of the centre, located in a sleepy town more than 100 miles from London and amid rolling countryside.
"It's taken a long while for this dream to become a reality. It is going to be very important."
England's record in recent years has been disappointing, never making it past the quarterfinals of a major tournament since Euro 1996 — which was also held in England.
The team is currently fifth in the FIFA rankings but is no longer regarded as a heavyweight of the international game, with players' inability to keep possession seen as the main reason for its decline.
The hope is that more and higher-quality coaches will be produced at St. George's Park, which will translate to future success on the pitch.
"It is a momentous day in our history," FA chairman David Bernstein said. "What has been achieved here is breathtaking. It is an inspirational training base for all our national teams and for coaches an Oxbridge (Oxford and Cambridge) of football.
"We expect to get a huge amount out of this, probably first and foremost the development of more and better coaches."
William and Kate initially spoke with England captain Steven Gerrard and Hodgson before walking across the practice pitch for a meet-and-greet with the rest of the senior squad — including Ashley Cole, who on Friday posted an offensive tweet criticizing the FA. William is the governing body's honorary president.
"St. George's Park is a concept totally new," William said. "It will provide more than just world-class facilities for our national team and more than a university from which hundreds of coaches will graduate.
"It will provide employment and a social hub for local people and will foster community spirit and purpose and hope throughout England."
England squads will be accommodated in a Hilton hotel, where players will have their own private dining area and games room.
"There is no better place to come to work," Gerrard said. "The place has blown me away. All the lads are buzzing to be here.
"Now we've got the best stadium in the world and the best facilities. We're taking away all the excuses the players might use in the future."
The centre has been in use for several weeks by younger age groups but was first sampled by England's senior men's team on Monday, ahead of World Cup qualifiers against San Marino on Friday and Poland next Tuesday.Suggest a correction
