Qolla l-Bajda Battery (Maltese: Batterija tal-Qolla l-Bajda or Fortina tal-Qolla l-Bajda) is an artillery battery in Żebbuġ, Gozo, Malta. It was built by the Order of Saint John in 1715 and 1716 as one of a series of coastal fortifications around the coasts of the Maltese Islands. It retained its original layout until the late 1970s, when it was converted into a discothèque and snack bar known as Rook (after the chess piece) and major alterations were made to the battery. The building, in the midst of a legal battle between the government and a private company, is now abandoned and in a dilapidated state.
Qolla l-Bajda Battery is one of only two surviving batteries on Gozo, the other one being Saint Anthony's Battery in Qala. It is not far from the northernmost point of the island, Reqqa Point, and as such it is the northernmost fortification in Malta. The battery is also known by a number of other names, including Xwejni Battery (Maltese: Batterija tax-Xwejni), Qbajjar Battery (Maltese: Batterija tal-Qbajjar) or the Castello.
