The abandoned Magheramorne quarry area is used as a filming location for the HBO TV series Game of Thrones. Castle Black, Hardhome and the Wall were filmed there, whereas scenes shot atop the wall were filmed inside the Paint Hall Studios in Belfast. The composite set (with both exteriors and interiors) consisted of a large section of Castle Black including the courtyard, the ravenry, the mess hall and the barracks, and used the stone wall of the quarry as the basis for the ice wall that protects Westeros. A functional elevator was built to lift the rangers to the top of the Wall. A castle with real rooms and a working elevator were built near a cliff 400 feet high, CGI fills in the rest to make the wall appear 700 feet high.[4] The area around the elevator was painted white to make it look like ice. George R. R. Martin said: "It's a pretty spectacular, yet miserable location. It is wet and rainy, and the mud is thick. I visited there; it really gets the actors in the mood of being at the end of the world in all of this cold and damp and chill".[5]
