Administratively El Wad is the capital of an annexe to the territory of Tuggurt.
These actions proclaimed so unmistakably Napoleon's intention of making Italy an annexe of France as to convince Francis of Austria and Alexander of Russia that war with him was inevitable.
In the centre rises a dome, fronted by two smaller cupolas; while a secondary dome, broader and loftier than the central one, springs from the annexe.
It was founded by Dr Dohrn in 1872; a large annexe was added to it a few years later on its western side, and a larger annexe on the eastern side was completed in 1907.
In shape it is oblong, with a many-sided annexe at the back.
