Masjid al-Nilein (al-Nilein Mosque)

From archnet.org:

Designed as a thesis project by a student in the department of architecture at the University of Khartoum, the mosque was selected for construction by the President of Sudan. It is a circular structure mounted by a lightweight aluminium space-frame in the form of hemispherical dome. The mosque interior is lavishly decorated with geometrically patterned timber ceilings and plaster work. Adjacent to the prayer space are twelve octagonal pavilions that house a school, library,and exhibition space.
