THE opening of Wales's new National Assembly building was "a moment for the whole of Wales to celebrate", the Queen said when she officially opened the £67 million building yesterday.

She was accompanied by the Duke of Edinburgh, the Prince of Wales and the Duchess of Cornwall at the Royal opening of the building in Cardiff. In a speech inside the Richard Rogers designed debating chamber, she told Assembly Members they had to ensure the building was worthy of similar respect to the Houses of Parliament.

"The skill and imagination of those who have designed and constructed this remarkable example of modern architecture have given you a dramatic setting in which to work," she said.

"It shows pride and confidence - in the future of Wales, in the future of democracy, and in the central role of the National Assembly in the life of the nation.

"It is now up to you, by giving meaning to the ideals and aspirations of those you serve, by expressing the spirit of your rich and ancient culture, by shaping the very future of this country, to make this National Assembly a true symbol of Wales."

She paid tribute to the building's impeccable environmental credentials, saying it "respects the stewardship of the world's environmental resources".

The design of the Senedd building, which AMs began using earlier this month, made it "accessible and welcoming", she said.

The Queen said: "It is grounded in the earth, but reminds us of the high ideals to which public service aspires."

She added: "I am delighted that this important occasion has drawn on the heritage and diversity of this land to mark the opening of this fine new building. It is a moment for the whole of Wales to celebrate."

The Royal party arrived about midday when the Queen and the Duke flew into Cardiff International Airport.

The sky cleared above Cardiff Bay, melting a dusting of snow, shortly before they arrived.

There was a fly past by four RAF Hawk jets and a 21-gun salute before the party entered the building.
