To solve defects that a charnel chamber lacks in strength against a pressure for having a lot of space in its inside, the structure of the charnel chamber is complicated and large so that, if an emergency arises, the collective carrying of the remains and memento is not easy, and a cinerary urn may be broken by vibration when being carried.

This permanent altar is so formed that a solid having six faces are bored with a plurality of cylindrical holes, and a cylindrical container with a screwing cap and the dimension corresponding to the bored cylindrical container insertion hole 13, in which the remains, the memento, and the like are put, is stored in the cylindrical container insertion hole in an incinerated bone storage chamber 11. This constitution can protect the remains from the external pressure such as an earthquake so as to solve the problem in the strength and simplify the structure of the incinerated bone storage chamber and collect the remains and the like in a saved space so as to facilitate the carrying.
