Nothing in the formal sense. After their suicide, the corpses of Adolf and Eva Hitler were removed from the bunker and taken outside. They were laid in the garden of the Reich Chancellery and doused in gasoline from a collection of cans that had been ordered earlier in preparation for this eventuality. About a half-dozen personnel were present at the beginning of the cremation, rending the Nazi salute over the corpses, but due to the recurring shelling of the area by the Soviets no one stuck around for long to watch the cremation, just checking back a few times to throw more fuel on. Beyond that, the history of the remains is covered here.
