This is actually a movie set, constructed in Ouarzazate, Morocco for the Jerusalem sequence in Ridley Scott 's Kingdom of Heaven (2005). By agreement with the town's government it remained standing after the film wrapped, and is a popular location for productions involving similarly medieval architecture. It was recently featured during Season 4 of the TV show Game of Thrones (2011). Despite being mostly complete, you can identify it as a movie set from the shot in the film, by noting the scaffolding on the bottom of the structure revealing an incomplete wall. A battering ram prop from Kingdom of Heaven (2005) can be seen next to this scaffolding.
