Prince Harry will be arriving in Lesotho onThursday (26 November) for the official opening of the Mamohato Children's Centre, set up by his children's charity Sentebale. The 31-year-old prince will reportedly pay tribute to his late mother Princess Diana and his former nanny by naming buildings after them.

Sky News reported that the centre's welcome block has been named after Olga Powell, Harry's nanny who passed away in 2012. "When Olga passed away the family donated the money that would have gone to flowers to Sentebale, that's why this building is in loving memory of Olga Powell," Sentebale's chief executive Cathy Ferrier said. Powell began working for the royal family when Harry's older brother Prince William was just six months old and remained a family fixture for 15 years.

Harry will be opening the new centre with his charity co-founder Prince Seeiso of Lesotho. The two royals established the charity, which works to meet the needs of children living with HIV, to honour their mothers, Princess Diana and Queen Mamohato Bering Seeiso. King Letsie III will unveil the new Momohato Children's Centre, which will provide services to young children.

While the new centre is named after Prince Seeiso's mother, the central dining hall will be named after Diana, Princess of Wales. "It's the place where all the children will gather three times a day (for meals) plus do games and drama and goodness knows what else — it felt like the right place to be in memory of his mother," Ferrier said.

"I'm hoping that they are quietly laughing or quietly smiling that we've come this far," Prince Seeiso told Sky News about their mothers. "I think Harry has mentioned some time ago that he hopes his mother is quietly comforted that he's doing what she would be expecting." He continued: "My mum, I have flashbacks of the days when I used to go from centre to centre with her and I was kicking and screaming saying 'mummy don't take me there, I don't want to go,' but it was a role that has led me to where I am today."

Following his trip to Lesotho, Harry will continue on to Cape Town, South Africa, where he will play in a charity polo match to raise funds for Sentebale. Harry will then launch a four-day tour of South Africa on official royal duties. The tour "will focus on a number of key themes, including understanding South Africa's recent history, the issues and opportunities for young people in South Africa today and the importance of wildlife conservation," Kensington Palace said.
