The oldest version of this name was "Preslava" (Slovak) / "Preslav(a) sburg" (German). It appeared for the first time in 907 (Battle of Pressburg) in the forms "Brezalauspurc(h)", "Braslavespurch" and "Pressalauspruch" and then around 1000 on Hungarian coins as "Preslav(v) a Civitas" (meaning Bratislava Castle). On the other hand, the exact location of Brezalauspurc is still disputed.
