The canal ring area of Amsterdam lays on more than 100 kilometers. With 1500 bridges linking 90 islands, the canal area is made of 5 ring canals, built at the beginning of the 17th century, and the historic centre (Centrum) of Amsterdam.
The area is really beautiful and full of historical treasure dating from the period where Netherlands and its maijor cities were a huge economic force. For the testimony it carries on and its beauty, the place really worths its WHS ranking.
