All the kings of Burundi were inducted into the Valley of Kings, at the confluence of the Mucece and Nyavyamo rivers. The route of enthronement was generally from Muramvya or Mbuye royal enclosure to the Mucece Valley. The procession was impressive: the queen-mother and the Crown Prince in the lead, then the principal princes of the country, the ritualists of enthronement, the priests of the Kiranga cult, the herds of cows, the carriers of all products of the country ( baskets of sorghum, hives, banana, beans, finger millet, beer, mead pots). Here, the new king planted three commemorative trees of his reign: the ficus, the erythrin and the dragon tree. They are centuries old trees, planted by four generations of kings and they are still visible on the site.
