Unfinished Northern Pyramid of Zawyet El Aryan

The Unfinished Northern Pyramid of Zawyet El Aryan, also known as the Pyramid of Baka, the Pyramid of Bakare, or the Pyramid of Bikheris, is the name archaeologists give to a large unfinished pyramid shaft at Zawyet El Aryan in Egypt. It is generally dated to the early or mid Fourth Dynasty of the Old Kingdom. Its owner is not known for certain, and while most Egyptologists, including Miroslav Verner, attribute it to a king known by the Hellenized name Bikheris, others such as Wolfgang Helck have doubted the attribution.
