Dlhé diely is one of the newest residential quarters of Bratislava. It is situated in Karlova Ves on a hill overviewing the Danube, Bratislava and Austria. Major area is filled with paneláks.
The territory was previously a park/wood near Karlova Ves proper. The park was known as Langetheile before 1950 and as Dlhý diel from 1950 to 1976; both Langetheile (German) and Dlhé diely (Slovak) literally mean "long parts" or "long divisions".
Dlhé diely is one of the more attractive quarters in Bratislava for housing, though recently big problems with traffic have been emerging because of large number of people living there (and more coming).
