You may have seen how Muslim & Christian bury their dead, you may have heard how Hindus use fire to burn the body of the dead person, but do you know what Parsi do with their dead bodies?
The orthodox and traditional method of getting rid of a corpse among Parsi was to through it to Vultures and other birds that ate the dead body within few hours.
They build towers and buildings far away from city and towns where the dead were thrown away for vultures and other birds.
That remained their official method until the population grow and these remote towers are building came within the city boundary because of expansion. Then they allowed to purchase land so that the dead may be buried there.
In India the Parsi community still uses the orthodox method though most have opted for better options such as burial and cremation.
