Dellia Battery (Maltese: Batterija tad-Dellija), also known as Vendôme Battery (Maltese: Batterija ta' Vendôme) or Pwales Right Battery (Maltese: Batterija tal-Lemin tal-Pwales), was an artillery battery in Xemxija Bay, limits of St. Paul's Bay, Malta. It was built by the Order of Saint John in 1715 as one of a series of coastal fortifications around the coasts of the Maltese Islands. It was demolished in 1924, but the coats of arms and inscription which were located above the main entrance still exist and are now a monument.
