Tomb of the Kings

The Tomb of the Kings (王家の墓, Ōke no Haka) refers an ancient tomb located in Arabasta's capital, Alubarna, wherein lies the tombs and graves of past kings of Arabasta. It is also the location of the Arabasta Poneglyph and can only be reached by a secret entrance revealed by turning a statue at the normal tomb. Inside, there is a hidden panel that can be activated to make the room collapse. It first appeared in Chapter 202 and an unknown episode.

The final battle between Monkey D. Luffy and Crocodile also takes place here. The room was forced to collapse by Nefertari Cobra in an attempt to kill Crocodile.
