This is a resource for those who are unable to travel, and also represents a legacy for future generations. Soon documentation and reproduction will be the only ways to enjoy many of the world's greatest monuments, which are slowly disappearing for a wide range of reasons including: climate change and natural disasters; illegal trade by logging, looting, poaching; mass tourism and travel industrialisation; mismanagement, wrong policies, lack of funds; modern development; shifting or growing populations; political instability, conflict and war; pollution.
