THe parts of the tomb built for Tausert have distinct phases. The first occured while she was Seti II’s queen and were done by his workmen. After his death, the second phase began under the reign of Siptah for whom she was regent. THe first burial chamber was done at this time. When Tausert assumed the throne on her own, the tomb was enlarged and updated to reflect her new royal status.

Sethnakht, of course, had his own tomb begun during his reign, but it was unfinished at the tim eo fhis death, so his son buried him in Tausert’s tomb and took his father’s as his own.
