From the northern tip of the Zürichsee, the Limmat River starts its brief journey to the Aare and, ultimately, to the Rhine—and it neatly bisects Zürich at the starting gate. The city is crisscrossed by lovely, low bridges. On the left bank are the Altstadt (Old Town), the grander, genteel section of the old medieval center; the Hauptbahnhof, the main train station; and Bahnhofplatz, a major urban crossroads and the beginning of the world-famous luxury shopping street, Bahnhofstrasse.
The right bank constitutes the livelier old section, divided into the Oberdorf (Upper Village) toward Bellevueplatz, and the Niederdorf (Lower Village), from Marktgasse to Central and along Niederdorfstrasse, which fairly throbs on weekends. Most streets around the Rathausbrücke and the Grossmünster are pedestrian-only zones.
Scattered throughout the town are 13 medieval guildhalls, or Zunfthäuser, that once formed the backbone of Zürich's commercial society. Today most of these house atmospheric restaurants where high ceilings, leaded-glass windows, and coats of arms evoke the mood of merchants at their trade. Often these restaurants are one floor above street level because in the days before flood control the river would rise and inundate the ground floors.
Zürich is officially divided into a dozen numbered Kreis (districts), which spiral out clockwise from the center of the city. Kreis 1, covering the historic core, includes the Altstadt, Oberdorf, and Niederdorf. Zürich West is part of Kreis 5. Most areas in the city are commonly known by their Kreis, and a Kreis number is generally the most helpful in giving directions.
