An unused quarry in Northern Ireland is the site of a film set for the HBO medieval fantasy series "Game of Thrones".
The set is alongside the edge of the quarry dig, which (after CGI enhancement) serves as "The Wall" in the story. The set appears to be under construction in this satellite photo.
In the Bing maps view, another set can be seen being built nearby to the northeast.
