There is neitherland norland. The country you probably mean is called "the Netherlands" (pl.). The most interesting subject from a physicist's point of view are presumably all the engineering efforts to manage water throughout the centuries and all over the country. There are also a lot of historical places, where famous physicists lived, e.g. astronomers like Huygens, Oort, the birthplace of Kuiper, etc. You can Google for museums or similar, if that is what you meant.
