The Tower of Silence is a the top of a small hill overlooking Aden's old town, the Crater, just before the steep slopes leading to the old volcano to start. It takes 45 mn from hotel Rimbaud to reach the tower, going amongst the burrows-like shacks of breeze blocks climbing towards the hills were are living the African refugees, then by a no-man's-land which is the territory of a band of skeleton stray dogs. The Tower is a pillar standing at the centre of two walled rings, used as funeral ground for Indian immigrants adepts of the Zoroastrian cult. Zoroastrians didn't believe in burying nor in incineration. To sent their dead to the other world, they were lying the corpses inside the walled rings, then were relying on vultures' hunger to dispose of them. An original + unusual place to visit, from where you have a splendid view on Aden's Crater.
