“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

A Vietnamese artist acting as a medium, performs the “Hau Dong” ritual at Viet Theatre in Hanoi January 16, 2016. For the first time, Vietnamese drama director Viet Tu has brought the ritual from religious temples to the theatre partly to draw tourists. The “Hau Dong” is a ritual where a medium puts on special costumes and tells stories of gods and heroes while being accompanied by “Chau Van” music, as part of the act of Dao Mau – the worship of mother goddesses in Vietnam. It is believed that the medium is capable of having a direct contact with spirits during the ritual. (Photo by Reuters/Kham)
