Prince Charles visited Durham and received an engagement card for Prince Harry and Meghan Markle.

On Thursday, the Prince of Wales stepped out in Durham. Prince Charles' first stop was the Church of St. Mary the Less that was originally built in the 12th century. Clarence House shared a number of snaps of the royal's visit at the place.

Prince Charles was greeted by the crowd warmly, who were armed with little Union Jack flags. On the said outing, he received a special present for his son, Prince Harry, and future daughter-in-law, Markle.

The students at The Chorister School, an elementary school located near Durham Cathedral handed Prince Charles an engagement card for the "Horrible Bosses" star and the Duke. It was covered with hearts with a sweet message that read: "To Prince Harry and Meghan, Congratulations on your Engagement!!!" People reported.

Prince Charles accepted the card with a big smile. He just reunited with Prince Harry at the International Sustainability Unit meeting to discuss the protection of the world's coral reefs on Wednesday.

For the said event, Prince Charles gave a speech about saving the coral reefs because 2018 is the International Year of the Reef. The Prince of Wales discussed the things that the organizations could do to improve the coral reef health.

Prince Harry was present to support his father and to learn more about the works being done for that specific environmental concern. "HRH was joined by Prince Harry, who wanted to find out more about the work being done to protect coral reefs from threats including climate change and pollution," Clarence House announced.

The father and son share the same passion for environmental protection and sustainability. In fact, Prince Harry is expected to pick up the baton for the new environment campaign from his dad.

In related news, Prince Charles is expected to take over the throne from Queen Elizabeth II. But aside from this, he is also likely to get the title of the Commonwealth Head. This title will not be automatically given to him, but several leaders and even the monarch want him for the position.

In 2015, Queen Elizabeth II visited Malta with Prince Charles and Camilla Parker Bowles. In her speech, Her Majesty said that she could not "wish to have been better supported and represented in the Commonwealth than by The Prince of Wales who continues to give so much to it with great distinction."
