Paris
The Paris Métro system was built in 1900 by engineer Fulgence Bienvenüe and architect Hector Guimard. The Métro covers over 198 kilometers/124 miles with 300 stations and 16 lines. Servicing over 6 million residents and tourists every day, the Métro was designed to be an efficient and reliable alternative to the congestion of traffic. Every building in Paris is less than 500 meters from a train station, so accessibility is never a problem. The 16 Métro lines are identified by their final destinations. A rider can simply select the appropriate line and take it in the direction s/he wants. The Métro stations are well marked, and there are ticket booths at most entrances.
