Berlin is a large city with several downtown centers that evolved during the 30 years of separation. Of Berlin's 12 boroughs, the 5 of most interest to visitors are Charlottenburg-Wilmersdorf in the west; Tiergarten (a district of the Mitte borough) and Kreuzberg-Friedrichhain in the center; Mitte, the historic core of the city in the eastern part of town; and Prenzlauer Berg in the northeast. Southwest Berlin has lovely escapes in the secluded forests and lakes of the Grunewald area.
