NL759 - Defence Line of Amsterdam (1996)

Brief Description

"Extending 135 km around the city of Amsterdam, this defence line (built between 1883 and 1920) is the only example of a fortification based on the principle of controlling the waters. Since the 16th century, the people of the Netherlands have used their expert knowledge of hydraulic engineering for defence purposes. The centre of the country was protected by a network of 45 armed forts, acting in concert with temporary flooding from polders and an intricate system of canals and locks."


"此防线建成于1883-1920年之间,在阿姆斯特丹 四周延伸135公里,是唯一一座为控制水量而建成的防御工事。自从16世纪起,荷兰人民为了防御目的,利用其水利工程技术人员特有的知识,为确保国家中心 部分的安全,在坝上建起了45个堡垒,并配有大炮用来防洪,还设有渠和水闸系统。"
