Visit Amsterdam, the capital city of the Netherlands, which features more than one hundred kilometres of canals, about 90 islands and 1,500 bridges. The canals are not only a testament to the successful city planning of the 17th century but a great way to get around the city. In the early part of the 17th century, with immigration rising, a comprehensive plan was put together, calling for four main canals. Three of the canals were mostly for residential development and a fourth, outer canal, was for the purpose of defense and water management. Visit Anne Frank's House, a historic house and biographical museum dedicated to Jewish wartime diarist Anne Frank.
