The visitor center contains history of the great flood of January 31, 1953 when the dikes broke and 1835 people died. In response to this, all the dikes and dams in The Netherlands were made taller and they also started the “Delta Project”. This is a dam/lock system built on the place where the Rhine, Meuse and Schelde rivers come together in Zeeland Netherlands. The dam is built so that it is only lowered/activated when there is bad weather. It took 30 years to complete and was built at a cost of $5billion. All of the rock and land fill had to be imported from other countries as none exists in the below sea level country of The Netherlands. Since installation in 1987, the dam has only been activiated around 20 times and no flooding has occurred. Not only had there been a huge flood in 1953, but in 1421, 6000 people died in flooding. The Delta Project has been cited as the greatest achievement of the Dutch people. It has resulted in dams, locks, secondary dams and structures. We walked on the dam and Norm even walked up, down, and on top of the steel catwalk. Wow. Afterwards, we met our boat and sailed to Rotterdam.
