In January 2006 I visited London and traveled via light rail to Dover. Dover Castle has stood overlooking the city since the 1200s. The “White Cliffs of Dover” are compact limestone cliffs that are only 20 miles from France. Called “Hell's Corner” by her residents and defenders, Dover was impacted by hundreds of long range artillery shells and air dropped bombs from 1939-1945. Dover Castle was an important military outpost, and it was expected that Hitler’s Operation Sealion (Seelöwe), the invasion of the British Isles, would start here.
It's an amazing place, helped by typical English weather of dark grey skies. France was obscured the day I visited, but it did help to take me bck to 1200 and see the castle through the years. Many more photos, including inside the wartime tunnels used for Operation Dynamo and Operation Overlord, will be posted as time allows. This page shows the museum of artillery around Dover Castle from World War II. Even with this arsenal, according to signs posted, there was much more emplaced during World War II. the big guns, railway carriages with 15-inch rifles, were not present at Dover Castle, but they were teh Castle's main armament, and frequent exchanges with German gunners at ranges of 40,000 yards were not uncommon.
If you get a chance to go to Britain, and are interested in World War II history, or history in general, please stop by Dover Castle. Walking on the grounds seems as if you can hear the many voices executed, accidentally killed, killed in war, and who suffered long posts in a shooting gallery. I was profoundly moved by the hundreds of years of history all around me.
