Young Blonde Girl Undresses A Yellow Dress In The Ruins Of Ancient Castle

Ancient cities were often highly militarized and fortified defensive settlements. In times of war they were the central focus of armed conflict and would be sacked and ruined in defeat. Although less central to modern conflict, vast areas of 20th century cities such as Warsaw, Dresden, Coventry, London and Berlin were left in ruins following World War II, and a number of major cities around the world – such as Beirut, Kabul, Sarajevo, Grozny and Baghdad – have been partially or completely ruined in recent years as a result of more localised warfare.
Entire cities have also been ruined, and some occasionally lost completely, to natural disasters. The ancient city of Pompeii was completely lost during a volcanic eruption in the 1st century CE, its uncovered ruins now preserved as a World Heritage Site. The city of Lisbon was totally destroyed in 1755 by a massive earthquake and tsunami, and the 1906 San Francisco earthquake left the city in almost complete ruin.
