The world of Westeros has arrived in Greenwich as the Game of Thrones: The Exhibition opened at The O2 yesterday.

The interactive showcase, at the Sky backstage area, is free to ticket holding Sky TV customers until February 12 and again from February 15 to 17.

Actor John Bradley, who plays Samwell Tarly in the show, was on hand to open the exhibition, which features nearly 70 original artefacts from the series as well as set-pieces from the fifth series which premieres on Sky Atlantic this Spring.

With more than 70 props and costumes from the fourth and fifth seasons and interactive elements at the exhibition, Game Of Thrones fans can fully immerse themselves in the fantastical world of Westeros.

A breath of flames from the dragon Drogon will engulf those fans foolish enough to stand in its way - a grisly death that can be captured on film for posterity - while others may prefer the experience of being "turned" by a White Walker, face frosted and eyes turned blue.

And a 4D "ascend the wall" virtual reality experience allows visitors to follow in the footsteps of Jon Snow and the Night's Watch and ride the Castle Black winch elevator to the top of the 700ft ice wall, before being attacked by wildlings.

Other exhibits include gowns worn by Missandei and Daenerys Targaryen, a Meereenese mask and the nails and hammer used to crucify the Masters of Meereen.

Eddard Stark's sword Ice is on display, as are Arya Stark's Needle and Jorah Mormont's blade and its peacock feather-decorated sheath.

Fans can also grasp the hilt of the 5ft 4in sword wielded by Gregor Clegane, The Mountain - but in anticipation of not all Game Of Thrones viewers being as big as the 6ft 9in actor Hafthor Bjornsson, the giant broadsword is held on a stand.

Bradley said: "I think that they see the show as something so fantastical and so out of this world, so when they actually encounter bits and pieces from the show they feel that they are in it and that a bridge has been built between them and people that they love."
