Visitors catching ferries from Dover to Calais
may be taking part in what is known as dark tourism.
The subject is to gain its own dedicated academic research centre at the University of Central Lancashire, focusing on the desire of some to see sites associated with death and destruction.
Such places may include concentration camps or sites like Ground Zero in New York, with the creation of the centre being a recognition of the growing interest in such events.
One example of this may be the battle sites of the two world wars in Europe, such as the Somme and Verdun.
The battle at Verdun in 1916 was so severe that the area was declared a zone rouge - with the villages of the area not being rebuilt because there was so much unexploded ordinance about and the destruction was so severe.
Tours of this and other battlefield can be undertaken to learn more about the destructive conflict that shaped the last century.
