Alongside the Queen, who also has a busy schedule this week, Princess Anne paid her respects by laying a wreath at a memorial garden dedicated to those who lost their lives in the tragic 1988 terrorist attack.
With other members of the royal family, like the Princess of Wales and the King, currently undergoing cancer treatment, and Prince William taking time off for the school holidays, the roster of working royals is noticeably reduced.
However, Princess Anne and her brother, the Duke of Edinburgh, managed to carry out a total of five public engagements in Scotland.
During her visit to Lockerbie’s Garden of Remembrance, Princess Anne appeared solemn as she walked through the memorial garden, offering her respects to the 270 victims of the terror attack on Pan Am Flight 103.
Fiona Armstrong, Lord-Lieutenant of Dumfries, warmly welcomed the Princess and highlighted the resilience of the community in the aftermath of the tragedy.
After paying her respects at the memorial, Princess Anne visited MacRebur, an asphalt contractor, and later attended the opening of new facilities at Browns Food Group in Kelloholm.
She also participated in a reception in Glasgow as the royal patron of the charity, Friends of TS Queen Mary.
Separately, the Duke of Edinburgh visited Westhill Men’s Shed in Aberdeenshire, an initiative that brings isolated men together for community-building projects.
The Duke engaged with members, touring workshops and interacting with electricians and engineers in attendance.
Princess Anne and the Queen are expected to continue their official duties in Scotland and Shropshire throughout the week, with the Queen also set to distribute Maundy money during the annual service as the King's representative.
The Queen is reportedly proud to take on an increased workload in the absence of other royals due to health reasons.
