BB, Prov. Noord Holland, Provinciaal Commando Bescherming Bevolking (PCBB).
At the Zijlweg in Haarlem as part of one of the provincial offices, there is an underground bunker that was used as a Provincial Command Civil Protection organisation "Bescherming Bevolking" (BB).
This organisation was too help and rescue civilians, provided additional fire services, warn for bombardments or ABC incidents.
From this Provincial CP they coordinated the actions in the province of Noord Holland and where in contact with come smaller CPs divided over the province (Kringen) and the HQ of the BB Utrecht.
On the pictures you see several radio transmitters that were used in those days to make radio contact with other command centres. When the BB stopped in 1985 all those transmitters where collected by the government except these in Haarlem. In the meantime the transmitters have been taken out and stored elsewhere!
The bunker was recently flooded with more than 1 meter water because the water pump was out of order. After this incident most of the water was pumped out , but there is still about 10-15cm water in it.
