Same here in the northern bit of the Low Countries, across the border from Uncle Goose: the only restriction is that you may not cause an obstruction in a public place. (Without having a permit that says you can, that is.)
Putting up a tripod in itself is not causing an obstruction. People have to start falling over it, with no other choice left, before it is.
On private property (including musea, churches, and what have you) the rules are set by the owner, of course.
I have yet to come across a privately owned bit of land (i hesitate to use the word "nature", since we have no such thing in our country. Everything is 'managed landscape' at best), opened to the public, that has a tripod or photography ban.
