The trip started in Kolkata. And from there we continued to Agra, Allahabad, Varanasi, and flew back to Denmark from Kolkata.
Allahabad and Varanasi are two of the most holy places for hindus. The transition from the present life to the next is very important in hinduism. And there is a whole cremation industry going on in Varanasi. If you get your ashes spread out in The Ganges from here, you can skip a step in the reincarnation proces.
