A walk through its cheery corridors, past a framed Prince of Wales crest emblem and Christmas cards from Charles and Camilla, leads to the bright and sunny day unit, where patients and volunteers are gearing up for an indoor garden party.
There’s Union Jack bunting, fluttering flags, William and Kate tea towels and buck’s fizz on ice in preparation for tomorrow’s big party.
Many of the staff and volunteers still have fond memories of the 1988 visit of Prince Charles and Princess Diana.
The Carlton Place hospice was gifted by the City of Glasgow to the couple in 1981 as a wedding present, the idea of then Lord Provost Michael Kelly.
Long-serving volunteers Margaret Forrest and Mary Lewis have been involved with the hospice project since it began, raising more than £100,000 over two decades of fundraising through their group Bearsden and Milngavie Friends of the Hospice.
Mary, from Bearsden, was introduced to the Prince and Princess of Wales twice.
She said: “Diana was just like any other person when talking to the patients. She was lovely.
“She was beautiful, but until you saw her face-to-face you didn’t realise how beautiful she was.”
Both veteran volunteers hope the latest royal wedding will open a new chapter in the 30-year history of the hospice.
Margaret, from Milngavie, who volunteers in fundraising and reception, said: “It’s wonderful -- very exciting. The fact that there’s a connection here to the royal family -- and William’s just his mother’s son.
The fact that Kate is wearing his mum’s ring makes it more special.
The hospice’s £1.4m day care unit was officially opened in a return trip by Prince Charles in 2000.
Unit’s manager, Ashleigh Moody, said staff had been offered the option of a public holiday for Prince William and Kate’s nuptials, but most have chosen to work.
Ashleigh, who joined the hospice before it had even opened, said: “We’ve always got a very positive atmosphere. It’s not just for the royal wedding.”
The day care centre, which has a small south-facing garden at the rear, can accommodate up to 20 patients a week.
The royal wedding tea party will be held indoors, as many of the patients are too frail to go outside.
Helen Shearer, from Pollok, has been coming to the day unit for four weeks.
Today, she’s enjoying a manicure from one of the volunteer beauticians, one of a host of activities on offer.
The 54-year-old, who has lung cancer, said of the tea party: “It will be good on Friday -- a chance for a knees-up.”
Volunteer Annette Fowler, 69, from Dennistoun, travelled to London by bus to be in the crowds for both the weddings of Charles and Diana and Prince Andrew and Sarah Ferguson.
The former Royal Infirmary nurse said: “It’s the royal family and we need to support them. We’re lucky we have a royal family in this country.”
Day care patient Betty Paterson, meanwhile, can cast her mind back to the wedding of Princess Elizabeth to the Duke of Edinburgh in 1947.
Her family and neighbours crowded around one tiny television set in Pollok.
The 78-year-old, who has just been told she’s clear of non-Hodgkin lymphoma, said: “The next door neighbour fixed up a TV for us to watch it.
“Fortunately, by Diana’s time, most people had a television and those who didn’t watched it in shop windows or went into their neighbour’s house. I just hope this wee girl will be just as beautiful.”
Plans were announced last month to build a new purpose-built Prince & Princess of Wales Hospice to open in 2016. Potential sites are being scouted in the south of Glasgow.
