Defense Line of Amsterdam - NETHERLANDS - UNESCO #759
What better way to defend the city of Amsterdam than using the web of water channels that surround it? To be honest I didn't knew about this defense line (and while traveling in Holland I don't remember see any of those forts) but it's really ingenuous. Thank you very much Ischa for making my UNESCO collection grow to 238 sites, I'm only missing 743 now (and only 3 Dutch sites). This postcard took 3 days to arrive!
Extending 135 km around the city of Amsterdam, this defense 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 defense purposes. The center 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.
