PRINCESS Anne visited Keyworth yesterday to open a new science building which will help researchers tackle some of the planet's biggest problems.

The Princess Royal met officials from the British Geological Survey as she opened the £6.2m William Smith Building in front of hundreds of staff who gathered to watch.

The princess was shown around the building, which is the largest wooden-framed open-plan office in the UK.

She saw presentations about the work done at the site, which includes finding ways to battle climate change, help developing countries use natural resources and deal with toxic waste.

As she unveiled a plaque outside, the princess paid tribute to the work done at the centre.

She said: "I thank you for allowing me to see something of the work you do. It's only a snapshot, I accept that, but it's really nice to see you have the investment to produce new buildings like this."

She said she felt it was important the public was aware of the work being done.

She said: "I hope you enjoy the new building. How sensible to name it after a man who started doing something so well – and you are still doing so well."

The building is named after William Smith, who produced the first geological map of Britain in 1812, travelling on horseback.

Prof John Ludden told the crowd the work done at the site would be greatly helped by scientists being able to interact more easily.

Edmund Wallis, chairman of the Natural Environment Council, said it was an honour to have Princess Anne visit.

He said: "You have turned this day from a special day to an important and memorable one."

Ian Jackson, head of operations at BGS, showed the princess a copy of an 1815 map by William Smith.

Mr Jackson said he was delighted Princess Anne had seen the building.

He said: "It's Her Royal Highness's third visit here. She came when it was a college and then when we were here in 1980. She is very interested."

The building, which has been in use since May, uses environmentally friendly technology.
