Cardiff Story museum visit for Duchess of Cornwall
The Duchess of Cornwall has officially opened the first phase of a new museum as part of Prince Charles's tour of Wales.
The Cardiff Story museum is dedicated to the city's history.
The royal couple were also hosting a community reception at their Welsh home, Llwynywermod in Carmarthenshire.
On Monday, the prince began his week-long tour with a trip to Aberdyfi in Gwynedd and the Centre for Alternative Technology in Machynlleth, Powys.
The Cardiff Story charts the history of Cardiff from the small market town of the 1300s to the current capital, all told through the eyes of the people.
Located on the site of the listed Old Library, the museum has a collection of more than 3,000 objects.
It opened its doors for the first time in April.
Cardiff council leader Rodney Berman said: "The Cardiff Story has been has been an ambition for the city for a number of years and the completion of phase one of the project is a reflection on the council's commitment to ensuring the rich history of Cardiff is preserved."
He said it was a privilege that the duchess was opening the museum.
To celebrate the royal opening, the Cardiff Story opened to the public for a special late viewing from on Tuesday.
The day also saw the prince meeting young people and business supporters during a reception for The Prince's Trust at his Llwynywermod home.
Up to 70 young people attended the reception, picked from more than 3,000 who have taken the Trust's five core programmes.
In the evening, the Prince and the Duchess were hosting a drinks reception for members of the local community.
The Prince also paid a visit to an anaerobic digester showcased by All Waste Services Ltd, in Llangadog.
The plant takes in a mountain of discarded food waste so that it can tap the valuable methane gas produced as it rots.
Children from Ysgol Gynradd Llangadog, the village's Welsh medium primary school, serenaded the Prince in Welsh on his arrival at the school.
