{ Answer}It's a tripoint, more or less - the place where the borders of three countries meet. In this case the borders are formed by the rivers Paraná and Iguazu. The countries are Brazil, Argentina and Paraguay, and the site in the puzzle is called Landmark of Three Borders, located in Brazil.

for the record:

that was a tough one

i can remember i saw the blue-white-blue flag and thought of argentina, but i did not search further

i've been more interested in the flag of the netherlands and checked those "dutch" places:
- Bonaire, Saba and Sint Eustatius
- Caribbean Netherlands
- Curaçao
- Suriname
- Sint Maarten

some have a few blue dots, some have a lot of blue dots, sigh...

when i wrote "the OP blue dot is of very poor quality" it's because i understood it was not the netherlands flag but the paraguay one!

plus, back in '96 i went to that place!

a great (non-dutch) puzzle indeed
