Ancestral worship is a cultural and religious practice, widespread in Africa and the African diaspora.
Cissy Nyakahuma, 51, from Uganda explains how she came to be the custodian of an ancestral site near the western town of Mubende.
I used to work in Kampala as a nurse but seven years ago, I felt something was missing. I consulted the spirits, my ancestors.
They told me to come here and be the caretaker of the Nyakaima Tree, be their voice. This is my heritage.
