Once round this bend, the main operational part of the bunker is revealed. The central corridor runs the whole length of the operational part. On the left is the main operations room and on the right are a number of smaller rooms. These include a smaller operations room, some domestic accommodation and some store rooms. Also on the right, above the rooms, is a storage loft. The ceilings are mainly about 14 feet high, or 18 feet where the walkway is missing. On the right hand side the ceilings are much lower to allow for the storage space above. The whole of this part of the bunker is encased in 10 to 14 feet of reinforced concrete and it is the strongest part of the whole structure. The origins of the fan mounted on an angle-iron frame are unknown but it might have been part of some original internal circulation system. We did plug it in and, after a little persuasion, and a quantity of oil, we did get it to turn over slowly. The door frame in the corridor is a late addition and was not very secure.
Looking back from the opposite end, the storage loft above the domestic rooms is more clearly seen as can the entrances to some of the smaller rooms. Even some of these had very strong doors fitted. Parts of the ceiling have fallen in at this point and other parts are very loose. It seems pointless but, as can be seen, many of the doors have been removed from their frames and left propped up in the corridor. It is not known whether this was done to make stripping equipment out easier or just some act of vandalism by those who broke in when the site was less secure.
