Barack Obama makes surprise visit to Stonehenge after NATO summit.

Barack Obama enjoyed a spot of sightseeing after the Nato summit with a surprise visit to Stonehenge, saying of the prehistoric landmark: "How cool is this?"

The US president shocked onlookers when he turned up unannounced at the monument in Wiltshire, squeezing in the visit after the final day of the alliance summit in south Wales.

Mr Obama, who asked helicopter pilot to make the unscheduled stop, told reporters that seeing Stonehenge had been on his "bucket list" of things to do before he died.

The president had just departed the conference - the first ever visit to Wales by a sitting incumbent of the White House - by paying tribute to the host country.

He said: "I want to thank the people of Newport and Cardiff and the people of Wales for welcoming me and my delegation so warmly. "It's a great honour to be the first sitting US president to visit Wales."

David Cameron weighed in, saying Wales had "done the UK and Nato proud."

Heather Sebire, English Heritage's Stonehenge curator, gave the president a tour of Stongehenge.

She said: "Mr Obama was fascinated by the story of the stones, what we know about them and the mysteries that have yet to be solved.

"He asked lots of questions about how old the monument is, how long it took to build it, and what was its purpose.

"He described the atmosphere around the stones as 'really special' and his visit to Stonehenge as 'a highlight of my tour'.

"He particularly loved seeing the colour and texture of the stones. It was a beautiful still evening and it was a privilege to show the US president around this unique monument which continues to inspire and intrigue people."

Mr Obama was met at the monument by English Heritage's Stonehenge manager Kate Davies.

She said: "We were honoured to welcome US President Barack Obama to Stonehenge.

"His office told us the president was very interested to see the iconic monument for himself. Every day people from all over the world make the trip to the ancient stones but this visit was a particularly special one."

Janice Raffle was similarly excited by the high-profile visitor.

She wrote on Twitter: "I can see president Obama! Any messages?"

After posting a picture apparently showing the President at the site, she added: "He waved to us!!"
