Amenemhat III Pyramid at Dashour.

Amenemhat III was the 6th Pharao of the 12th Dynasty. This Pyramid lies 800 meters East of the bent pyramid at Dashour. It apparantly started collapsing as it neared completion after 14 years of construction. It is largely built of mudbricks and no stone structural elements are visible other than a few casing blocks.
Several other 12th Dynasty Pharaos built pyramids at Dashour.
The local Antiquities discourage the longish hike accross the desert, but can be encouraged to look the other way.
