The US airforce base housed cruise missiles in the 1980s and early 1990s, and for 18 years women staged a protest there.

Now, for the first time in 60 years, the public will be allowed to wander round the 1,200-acre site, which has been out-of-bounds since it was taken over by the wartime government of 1941.

The US air force took over the base in the late 1960s. Throughout the '80s, the nuclear protest at Greenham common became the symbol of the anti-nuclear movement in Britain.

Trespassers risked being shot.

But on Saturday the fence was cut down with a ceremonial pair of bolt-cutters to mark it being returned to public space.

West Berkshire Council bought the base in 1997 and the area will now be classed as a Site of Special Scientific Interest.

"The reopening of the commons to the public is a great achievement," said council leader Dr Royce Longton.

"It is symbolic of this council's commitment to preserving the best of our countryside and wildlife habitats to be cherished for generations to come." More than 1m tonnes of concrete were dug up as the former air base's runways were removed, and a huge underground fuel tank has also been taken out.

However, the control tower remains and will be developed as a heritage centre.

The council also plans to buy the three remaining missile silos from the MoD in June next year.

Former Greenham protestor Jill Truman, who made numerous trips to the base between 1982 and 1992, told BBC News Online: "I vividly remember the horrible, horrible barbed wire - but also the sense of community. There were no leaders. It was tremendously empowering for women.

"The thought that people can now walk freely there - where the countryside is so beautiful - is a marvellous feeling. It has always been common land after all."
