The Grand National springs to mind as the yearly highlight of the “sport of kings” – thoroughbred steeds and their brave jockeys triumphing (or failing) over gruelling courses and high-fenced adversity. And now steeplechase enthusiasts can add another event to the annuls of great sporting occasions, namely the Stuttgart rabbit show jumping.

“Dover Castle is a medieval castle in the town of the same name in the English county of Kent. It was founded in the 12th century and has been described as the “Key to England” due to its defensive significance throughout history. It is the largest castle in England.

The outbreak of the Second World War in 1939 saw the tunnels converted first into an air-raid shelter and then later into a military command centre and underground hospital. In May 1940, Admiral Sir Bertram Ramsey directed the evacuation of French and British soldiers from Dunkirk, code-named Operation Dynamo, from his headquarters in the cliff tunnels”. – Wikipedia
