The Canterbury Bunker is an old underground Brigade Command Center that was decommissioned around 1945. The owner had previously found and opened up the west entrance with the help of KURG and this return visit was to explore the newly opened up east entrance. When the first entrance was opened up, the passage having been completely sealed for many years, was full of bad air from rotting wood and had to be well ventilated before exploring was possible. The air in the east passage was well ventilated before we entered and presented no problems

The west entrance, an opening near ground level, leads down a flight of 59 steps then along through an air lock. As can be seen in the diagrams to the right the tunnels were constructed using two methods and although all the tunnels using the arched RSJ and corrugated sheeting have survived virtually intact the tunnels using the pit prop method have collapsed and are totally inaccessible.

The west passage was blocked after approximately 60’ where the arched roof stopped, but it was possible to enter the latrines on the right hand side after a little digging. The east entrance being slightly higher up has a flight of 66 steps down and can be entered to a length of 120‘. This is also blocked by a collapse where the arched roof stops. Half way along this passage a similar set of latrines can be entered on the left hand side and opposite this can be seen the collapsed passage connecting to the west entrance passage.

It was hoped it would be possible to enter the engine room beyond the end collapse but due to the fact there was a 12’ void above the collapse and the passages are dug in Thanet sand, its was decided this would be too dangerous, so no further exploration was possible.
