Yes the Netherlands is or can be wonderful eeh, the one from the photo is just how they pictured the new to build mountain of course, but it probably is never going to happen because according the article it would be way too expensive to build one.
And had to look up the word shibboleth 
and it's really very interesting and the person who told you was right, (a shibboleth is sort of a 'password') and the word 'Scheveningen' was used to figure out if someone was actually a German or really Dutch and reading the examples the Fries example probably is one of the most famous:
Bûter, brea, en griene tsiis; wa't dat net sizze kin, is gjin oprjochte Fries (
example (help·info)) means "Butter, rye bread and green cheese, whoever cannot say that is not a genuine Frisian" was used by the Frisian Pier Gerlofs Donia during a Frisian rebellion (1515–1523). Ships whose crew could not pronounce this properly were usually plundered and soldiers who could not were beheaded by Donia himself.
It's really awesome how much we all learn about not only our families but also about the world and History here at WikiTree eeh.
