Berlin’s a large city and its layout, lacking a single ‘city centre’ may be confusing at first. The former ‘eastern’ centre is located around Alexanderplatz, whereas the former ‘west’ had its centre near the Zoologischer Garten station. Although both are linked by frequent S-Bahn and U-Bahn lines, getting from one to the other is likely to take half an hour, which means you’d be best of planning ahead, thereby attempting to focusing your activities to either sides of the city each day. On another east-west note, you may find it difficult to know whether you’re in the ‘east’ or ‘west’. Whereas the Soviet building blocks are generally easy to spot, it’s not always as easy and differences between the two have diminished since the fall of the Wall in 1989. Even the Ampelmännchen, which are now world-famous, have in recent years been placed in the former west and therefore cannot guarantee your whereabouts.
