Three years ago, Princess Kate paired with the National Portrait Gallery for her COVID-19 pandemic photo project to capture how British people — from ordinary families to health workers — coped with the challenging and often tragic times. It culminated in thepublication of a bookHold Still: A Portrait of Our Nation in 2020.

“When we look back at the COVID-19 pandemic in decades to come, we will think of the challenges we all faced – the loved ones we lost, the extended isolation from our families and friends and the strain placed on our key workers,” Kate wrote in the book’s foreword, explaining why the project was so important to her. “But we will also remember the positives: the incredible acts of kindness, the helpers and heroes who emerged from all walks of life, and how together we adapted to a new normal.”

“Through Hold Still, I wanted to use the power of photography to create a lasting record of what we were all experiencing – to capture individuals' stories and document significant moments for families and communities as we lived through the pandemic,” she continued. “I hope that the final 100 images showcase the experiences and emotions borne during this extraordinary moment in history, pay tribute to the awe-inspiring efforts of all who have worked to protect those around them, and provide a space for us to pause and reflect upon this unparalleled period.”
