Prince Harry visited the site in Huambo, which has become a “bustling community” since Diana’s campaign.
Wearing body armour, he also visited a partially-cleared minefield nearby and set off a controlled explosion.
Diana captured global attention when she walked through the live minefield in 1997.
She never lived to see the full impact of her visit – such as the signing of an international treaty to outlaw the weapons – as she died later that year.
