 The protestors consisted of nine smaller camps at various gates around the base.Camps were named after the colours of the rainbow, as a way of contrasting against the green shades of the base.The first camp was called Yellow Gate, and others included Blue Gate with its New Age focus; Violet Gate with a religious focus; and Green Gate, which was women-only and did not accept male visitors.The last missiles left the base in 1991 as a result of the Intermediate-Range Nuclear Forces Treaty, but the camp remained in place until 2000, after protesters won the right to house a memorial on the site.
