On 12 December 1982, 30,000 women held hands around the 6 miles (9.7 km) perimeter of the base, in protest against the decision to site American cruise missiles there. Source: https://en.wikipedia.org/wiki/Greenham_Common_Women%27s_Peace_Camp

From Peter Gelderloos, Anarchy Works:

In September 1981, a group of Welsh women formed a similar camp [to Scotland's Faslane Peace Camp], the Greenham Common Women’s Peace Camp, outside an RAF base housing cruise missiles in Berkshire, England. The women were forcibly evicted in 1984 but immediately reoccupied the site, and in 1991 the last missiles were removed. The camp remained until 2000, when the women won permission to set up a commemorative memorial.
