10 euro - Dutch Water Defence Lines

Did you know that the Netherlands has a unique World Heritage with water as an ally? As the only large scale system of floodplains, dikes, locks and forts in the world, The Dutch Water Defence Lines perfectly illustrate how the Dutch handled the water – a practice that dates back to the Middle Ages. First, they achieved this by enabling them to live and grow food in the marshy land. Later, they also used water to defend cities. It all started with the Old Dutch Waterline, established in 1672. The New Dutch Waterline built on this: construction began in 1815. Construction of the Defence Line of Amsterdam started in 1880. In 1996, the latter received Unesco status. In 2021, both waterlines came together as the Dutch Water Defence Lines and since then they form one world heritage. With the Dutch Water Defence Lines, water went from being an enemy and challenge to ally. With a series of rivers, sluices, dikes and canals, land could be flooded: this could effectively stop enemy attacks. This interplay of technology, ingenuity and water formed the defence of the rich west of the Netherlands. Today, the Dutch Water Defence Lines World Heritage Site is still very much alive. The forts are not only a hotspot for biodiversity, but volunteers are actively involved in promoting this World Heritage site through guided tours, maintenance and more.
