[1] Ascending to the throne in 1897, Auguste Manga Ndumbe created a large plantation of cocoa and palm oil in Mungo on the effluents of the Kamerun-Wui river, so as to compensate for the decline of the Douala economy based on the trade monopoly with the hinterland.

His son and heir Rudolph Douala Manga Bell reigned from 1908 to 1914, with his wife Emma Engomè Dayas.

Alexandre Douala Manga Bell, son of the late Rudolph, celebrated as a hero and martyr, chose to live in Bali rather than this mansion.

Known today as Le Parc des Princes, this compound includes the Bell's Chefferie.

Since 1920, the old mansion has been occupied by a long list of inhabitants and is still owned by the Bell royal family.
