Timisoara is considered Romania's most cosmopolitan city, with western European cultural influences and progressive aspirations. This was the first European city to install street lighting, and the first to run off hydroelectric power. It was also the second European and the first city in Romania with horse drawn trams in 1867. It is surnamed "Little Vienna" because the entire city center consists of buildings built in the Kaiser era, which reminds one much of the old Vienna. The old city consists of historic city quarters with several historic squares and proms. These are: Cetate, Iosefin, Elisabetin, Fabric. Numerous bars, clubs and restaurants have opened in the old center in the fine old baroque square.
