St John Cymru is celebrating '100 years of being there' for the people of Wales.
Established on 1 March in 1918, the nation's leading first aid charity was there to help wounded soldiers in World War 1.
Over the decades, volunteers have supported Welsh communities through the lows, such as the Aberfan disaster, and through the highs of Wales' Grand Slam wins.
As part of the charity's centenary celebrations, a replica WW1 ambulance will visit major events and school groups across Wales to highlight the history of the organisation, while also raising awareness of the importance of learning first aid.
Julia Hobbs, Chief Executive for St John Cymru, said:
"It's an incredibly exciting year for us and I hope everyone will get behind our celebrations and share their stories with us.
"We have set up a special website to capture people's memories of St John Cymru over the last 100 years and we can't wait to find out how our volunteers have made a difference to you.
"With the support of the people of Wales, we can make sure St John Cymru continues to be there."
