Rawda Island Nilometer

مقياس النيل بالروضة

A ninth-century Abbasid flood gauge at Rawda Island's southern tip: a stone well with a marked marble column and spiral stair.

Why go

Commissioned under the Abbasid caliph al-Mutawakkil in 861, this structure measured the Nile flood, which in turn set irrigation work and tax levels. Visitors look down into a stone-lined well where an octagonal marble column carries the measuring marks, with Qur'anic inscriptions about water and plenty carved into the walls and a stair spiralling to the bottom. The Ministry describes it as the oldest post-conquest building in Egypt surviving in its original form. Later dynasties restored it, and medieval sultans attended the flood festival held here.
