Facts about Amsterdam Canals
Amsterdam, capital of the Netherlands, has more than one hundred kilometres of canals, about 90 islands and 1,500 bridges.
The three main canals, Herengracht, Prinsengracht, and Keizersgracht, dug in the 17th century during the Dutch Golden Age, form concentric belts around the city, known as the Grachtengordel. - wiki travel
