HIT TV series Game of Thrones has been filmed in Fermanagh’s Marble Arch Caves.

Such is the demand for HBO’s most popular series, US President Barack Obama had an advanced screening of the fourth series in the White House.

American demand for the premiere of the fourth series reached fever-pitch on Saturday evening, with 6.6 million viewers tuning in, causing HBO’s live streaming channel to crash. UK viewers tuned in to SKY Atlantic on Sunday night for the epic fourth series.

Famous for being shot in Titanic Studios, Belfast, it is a little-known fact that Game of Thrones was also on location in Fermanagh.

Pollnagollum Cave is situated in Belmore Forest, part of the Marble Arch Caves Global Geopark. Irish for “hole of the doves”, the cave is fed by a waterfall toppling down from the top of a limestone cliff and is swollen to a torrent during harsh weather. Visitors to the area can follow the Belmore Forest walk which leads to a viewing point for the cave.

In the fourth episode, the cave is used as the hollow hill, the hideout behind a waterfall, where Arya Stark and Gendry meet Beric Dondarrion and the ‘Brotherhood Without Banners’.

Speaking in the Assembly this week, Tourism Minister Arlene Foster said an agreement between HBO and Tourism Ireland will mean that Tourism Ireland will “be able to access all [HBO’s] Facebook and Twitter feeds to reach their fans across the world.” She added: “Some Members may now realise that it happens across Northern Ireland from the Marble Arch caves, which, of course, I want to talk about, up to the north Antrim coast and down to Castleward. All those areas will be covered in this publicity. It is a good news story and one that I hope we can benefit from.”
