00:00:00nearly one third of the Netherlands lies
00:00:03below the sea level while the first
00:00:06barrier became operational in 1956 it
00:00:09wasn’t until several decades later in
00:00:111986 that the eastern shelled storm
00:00:14surge barrier became operational it is
00:00:17one of the largest structures in the
00:00:19world and it is actually an open damp
00:00:21originally plans for a closed damn were
00:00:24criticized because all of the saltwater
00:00:26environment of the area would cease to
00:00:28exist instead the open damned allowed
00:00:32gates to open and close 62 of these
00:00:34openings allowed as much salt water to
00:00:37pass through per time
