The body of Sir Frederick Edward Kabaka Mutesa ll the King of Buganda and the first president of Uganda lies in state in a glass coffin at Namirembe Cathedral in Kampala.
The body was in a good state despite having been buried in Kensel Cemetery London for 2 years , before being exhumed and returned to Uganda.
Kabaka being a Royal, had been buried in London in a lead lined coffin. Many royals, including British, are typically been buried in such coffins.
This is because they can be sealed airtight which greatly slows the decomposition of a body. Because of the lead lining the coffins are normally heavy. Princess Diana's lead lined coffin weighed 250 Kgs.
One Welsh guard who was a pall bearer said they trained for the duty by carrying a coffin packed with sandbags over a bridge, to the point that "our shoulders were all getting quite bruised".
