The problems of tomb construction can be seen with the tombs of Ramesses III and his father Setnakhte. Setnakhte started to excavate KV11 but broke into the tomb of Amenmesse, so construction was abandoned and he instead usurped the tomb of Twosret, KV14. When looking for a tomb, Ramesses III extended the partly excavated tomb started by his father. The tomb of Ramesses II returned to an early style, with a bent axis, probably due to the quality of the rock being excavated (following the Esna shale).
