 The tombs gradually became more regular and formalised, and those of Thutmose III and Thutmose IV, KV34 and KV43, are good examples of Eighteenth Dynasty tombs, both with their bent axis, and simple decoration.Perhaps the most imposing tomb of this period is that of Amenhotep III, WV22, located in the West Valley.It was re-investigated in the 1990s by a team from Waseda University, Japan, but it is not open to the public.
