White Pyramid of Amenemhat II (Dahshur)

12th-Dynasty 'White Pyramid' of Amenemhat II (c. 1929–1895 BCE), so-called for bright Tura-limestone casing (now stripped) contrasting with later dark Dahshur mudbrick pyramids. Base ~50 m (documentation fragmentary; Lepsius estimated 50–82 m; recent magnetometry suggests 50 m with sand core). Ruinous heap 8 m high, heavily quarried; core contained limestone and sand fill, western side yielded foundation deposit with Amenemhat II name. Substructure flooded, little survives.

Excavated cursorily by De Morgan 1894–95 who found only dispersed limestone chips and statue bases. Rare evidence of early 12th-Dynasty transition from stone Giza-type to mudbrick-sand technique. Adjacent to plateau track, heavily pitted by robbers.
