Meidum, Maydum or Maidum (Arabic: ميدوم, Ancient Egyptian: Mr(y)-Jtmw, lit. 'beloved of Atum', Ancient Greek: Μοι(ε)θυμις) [1] is an archaeological site in Lower Egypt. It contains a large pyramid and several mudbrick mastabas. The pyramid was Egypt's first straight-sided one, but it partially collapsed in ancient times. [2]
He then transformed the eight-step E2 pyramid into a true pyramid (E3) which stood between 92 and 95 metres high, with a base length of 144 metres. Today, the pyramid has the appearance of a three-step structure emerging out of a massive mound of rubble and debris surrounding it. This tower is, in fact, most of the core of the pyramid.
The pyramid of Meidum is one of the three pyramids ascribed to Sneferu (the other two being the Bent Pyramid and the Red Pyramid at Dashur). It is often known as the “collapsed pyramid” because of its ruined state.
