The Magere Brug (Skinny Bridge) in Amsterdam is the most popular and photographed bridge of the city. It crosses the Amstel river between Keizersgracht and Prinsengracht. It is called the Skinny Bridge because it used to be so narrow that it was hard for two pedestrians to pass each other. The original bridge was replaced by a wider bridge in 1871 but its nickname "Skinny Bridge" stayed.
