De Blauwe Aanslag was a squat and self-managed social centre in the Dutch city of The Hague. The oldest part of the building was built in 1886. The large building formerly housed tax offices and was occupied in 1980. When the local council took over the ownership of the building, it was agreed to renovate it in three stages, with the squatters living there. However the plans changed and since 1995 the council decided to widen the roads next to the building; for this reason the squat needed to be demolished. After many efforts to block the demolition with lawsuits, the squatters were evicted by military police on 3 October, 2003.
