Is there a website that list the locations of air raid shelters,AA gun sites and pill boxes in England during WW2?
Better than that, there is an overlay for GoogleEarth available here, from this thread. Once you've loaded it in GoogleEarth, you can tick it on or off from the left-hand menu. I tend to leave it off until I've zoomed into the area of interest, then turn it on. It's a very large dataset and does make the PC chug a bit.
