Nearby is an old limestone quarry currently owned by Lafarge. Extraction of limestone from the quarry, for use in the Magheramorne cement plant, ceased in 1980. The high point for limestone extraction at Magheramorne was in the 19th and 20th centuries. In the 19th century a mission church for labourers at the limeworks was established and became a Presbyterian Church. In September 2009, Lafarge obtained outline planning permission for redevelopment of the quarry and cement works, including a new eco-friendly village and a major cycling centre mainly in the quarry. A regeneration plan will transform the quarry into a nature conservation, leisure and housing area. The 75 hectare quarry will be the home of a World Cycling Centre and the All-Ireland Scuba Diving Centre if the plans go ahead. The area of Larne Lough that was used to ship cement out of Magheramorne is now used as a marina.
''Game of Thrones''
The abandoned Magheramorne quarry area was used as a filming location for the HBO TV series Game of Thrones. Castle Black, Hardhome and The Wall were filmed there, and battlements were built there to serve as King's Landing's defences during the Battle of Blackwater Bay; scenes shot atop the wall were filmed inside the Paint Hall Studios in Belfast. The composite set 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 high, CGI fills in the rest to make the wall appear high. 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".
