The five-month Monte Cassino campaign in central Italy is one of the best-known European land battles of World War Two, alongside D-Day and Stalingrad.

Cassino was an unusual campaign for World War II in that its outcome was not reliant on sweeping movements or the use of tanks or aircraft - but by old-fashioned boots in the mud, whether capturing the town of Cassino after months of grinding urban warfare (a Stalingrad in miniature) or scrambling up the steep mountain to seize the heights and the religious complex on top of Monte Cassino.

Monte Cassino Abbey was painstakingly rebuilt after the war (its baroque chapel remains incomplete) and is now a World Heritage site. An hour south of Rome, it is visited each year by up to one million tourists and pilgrims from around the world.
