Just outside the city of Yazd, there are two Towers of Silence. According to Zoroastrian beliefs dead bodies were not buried but left in these towers to be eaten by the vultures. This practise by the Zoroastrian to use these towers was to keep the earth clean from the dead bodies.
However, these towers have not been used since 1960s. These towers were built away from population centers to avoid contamination. In 1970s, the practise of leaving dead bodies in open was made illegal.
There were several buildings close to the Tower of Silence but they were no longer in use. A path leads to top where southeastern tower sits on top of a barren hill. A small door opens into a circular tower with an open pit in the middle. This is where bodies were left so birds could eat them.
