Charles' investiture as Prince of Wales happened back in 1969, when he was just 21. The ceremony took place at Caernarfon Castle, in Wales, and occured 11 years after he was originally given the title, as he was so young at the time when his mother became the Queen.

To date, Prince Charles is the longest-serving Prince of Wales, so celebrating 50 years since his investiture is sure to have been a special time for both him and Camilla over the last few weeks.

To mark the big milestone for him, Prince Charles and Camilla have been busy touring Wales over the last few days. Most recently, the couple stopped off in New Tredegar, to meet with local school children there.

Prince Charles and Camilla have also spent time in Cardiff and Swansea during their annual week of celebrations in Wales.
