Calum's Cabin is a charity that many Scots touched by cancer have benefitted from.
The organisation provides two peaceful retreats on the Isle of Bute for young cancer patients and their families.
Since 2007 youngsters living with the heartbreaking disease have been able to come to picturesque Rothesay for a relaxing break away from reality with loved ones.
But a heartbreaking loss in the town is the story behind the beginning of Calum's Cabin 15 years ago.
The family who created the retreat were left bereft following the passing of their 12-year-old son.
Calum Speirs was diagnosed with an inoperable brain tumour only a few days after his symptoms were noticed.
The schoolboy passed away just over a year later, on February 16 2007.
Calum's wish was for a holiday retreat to be built near their home where children with cancer could come to make memories.
In the wake of his tragic passing, Calum's Cabin was created.
Fifteen years later the charity has helped hundreds of families enduring the heartache of the cruel disease.
To mark their anniversary, Calum's mum Caroline released a poignant statement.
She said: "Sixteenth of February, 2007; the day that changed us forever.
"Fifteen years since Duncan, Jenna and I had to say goodbye to our courageous, loving, funny, mischievous, clever, kind, gentle and inspirational son and twin brother.
"How can it be 15 years?
"The ache in our hearts each day grows larger.
"How have we managed to survive 15 years (5478 days)?
"So much has changed, so much as happened but we know you are with us every step of the way."
Caroline added: "Fifteen years ago today Calum's Cabin became a reality and so many families have been helped, supported and guided.
"Calum's Cabin, as you all know was Calum's idea, he wanted to keep us all busy and keep helping others.
"Today and everyday we are a family of four, always have been, always will be.
"Calum Speirs we love and miss you with all our hearts, to the moon and back, always and forever."
Calum's Cabin has expanded since it first opened, securing a second cabin nearer Rothesay town centre.
Jenna was crowned our Sunday Mail Great Scot of 2008 for her dedication to fulfilling her brother’s dream.
In 2017 she paid tribute to her late twin brother to mark the 10-year anniversary.
Brave Jenna said: “Calum will always be part of me.
"We are two halves of the same whole and when he died I knew I had to live on for the both of us, working twice as hard, having twice the fun.
“He was an inspiration to me and everyone who knew him, and he thought of others right until the end.
“He may only have been here for 12 years but he inspired more people in that time than most do in a lifetime.
“It’s as if he knew his time was short and he had to pack it all in.
"Now, thanks to his legacy, Calum’s name is never far from people’s lips and even those who never met him feel he has been a part of their lives.”
Calum's legacy lives on as online followers hailed him, his family and Calum's Cabin for all they've achieved over the years.
One wrote: "What a legacy Calum has left behind and what an inspiration you all are to all those families going through the same.
"He would be so proud of you."
Another added: "I am thinking of you all and remembering Calum.
"What a special boy he was and what a legacy, one that has helped countless numbers of children and their families."
A third commented: "It was an absolute honour to have met Calum and yourselves.
"Calum has been such an inspiration to a lot of people.
"I wish you all the love and peace that you all deserve."
