History
According to Calgara, the bell was created to tell the world that "we are here", showing their ancestors the way back to their island as well as to signify to intruders they are not afriad of them. It represents the days of Shandoras past glory.

Norland orginally found Jaya island by listening to the sound of the bell.

The song was heard once more when Luffy defeated Eneru by knocking him to the bell.
