Kottbusser Tor (German pronunciation: [ˌkɔtbʊsɐ ˈtoːɐ̯] (listen)) is a Berlin U-Bahn station located on lines U1, U3, and U8. Many Berliners use the affectionate term Kotti (German pronunciation: [ˈkɔti] (listen); see Berlin dialect). It is located in central Kreuzberg. The area has a bad reputation for the relatively high, mainly drug-related crime rate, instances of which have recently[when?] become quite rare in most other parts of the district[citation needed]. The original Kottbusser Tor was a southern city gate of Berlin; the road through the gate led via the Neukölln suburb to the town of Cottbus. Trivia - K and missing h (Cotbusser Thor) rely to a language reform at begin of 20th century. See e.g. Stralauer T(h)or, or Cölln and Neukölln. From Wikipedia
