A crematory urn that displays inside condition comprises an urn body, a preserving material, and a detection device. The urn body is formed in polygonal shape and has an internal receiving space and a storage space in communication with the receiving space. The receiving space receives therein bone ashes. The preserving material is arranged in the storage space to maintain the receiving space in an environmental condition that prevents the bone ashes from deterioration, mildewing, and getting odorant for a period of time.
