Qolla l-Bajda Battery is an artillery battery in Żebbuġ, Gozo, Malta. It was built by the Order of Saint John between 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 and major alterations were made to the battery. The building is now abandoned and in a dilapidated state, being in the midst of a legal battle between the government and a private company.

Żebbuġ is an administrative unit of Malta, in the northwest coast of the island of Gozo. It is located close to Għarb and Għasri and is built on two hilltop plateaus, Ta' Abram and Ix-Xagħra taż-Żebbuġ. The fishing port and tourist resort of Marsalforn lies within the Żebbuġ Council. The village has a population of 2,956, which makes it the fifth largest in Gozo, after Xewkija.
