Diamond Jubilee: Queen in Wales in 1970s
The official opening of the University Hospital of Wales in Cardiff brought the Queen to Wales early in the 1970s.
The hospital had been 25 years in the planning, with the aim of uniting medical practice and teaching on one site.
Groundworks had begun nearly a decade earlier in 1963 on the site of the dental hospital, with the first dental students starting their courses in 1965.
The following year, construction started on the main hospital, and the first patients were admitted in 1970.
The Queen and the Duke of Edinburgh arrived in November 1971 to officially open the hospital.
They were back in Wales two years later at Aberfan, near Merthyr Tydfil, which in 1966 had suffered one of the worst mining disasters in Welsh history.
A coal waste tip had fallen down the mountain onto Pantglas Junior school and nearby houses, killing 116 schoolchildren and 28 adults.
The Queen had visited just days after the disaster.
In 1973, she returned to open a community centre in the town, and lay a wreath at the Aberfan Memorial Garden.
Speaking at the unveiling of the centre, she said: "It stands as a symbol of the determination that out of disaster should come a richer and fuller life."
In 1977, along with the rest of the country, celebrations were being held across Wales to mark the silver jubilee.
The Queen went to Harlech Castle in June, the first reigning monarch to visit since the castle was built by Edward I, 700 years previously.
The royal couple then moved on to the sunny seaside town of Llandudno and met locals and tourists alike in a walkabout on the seafront.
