                       Nevertheless (or maybe because of this) riding a bicycle in Athens has become lately some sort of a political (counter-)action, especially by young people with an alternative lifestyle.

                       Small rides are safe though in the long network of pedestrian streets around the Historical Centre of the city and can be quite enjoyable indeed.

                  <h4>Metro</h4>
                  <p>
                      The Athens Metro has 3 lines. Line 1 (the Green line) started operation in 1869, making it the second oldest underground system in the world after the London Underground.
                      Lines 2 and 3 opened in 2000 and increased the Metro’s popularity due to its speed, cleanliness and security.
                      Today’s Athens underground connects important landmarks of the Greek capital, such as the Acropolis, Athens Airport, Port of Piraeus, Central Railway Station and Olympic Stadium, in addition to connecting downtown Athens with the suburbs.
                      Archeological exhibits found during Metro’s construction and modern works of art are exhibited in many stations.
                      All stations are fully accessible to disabled persons with elevators in every level and platform and most of train cars are air-conditioned.
