I don't know how it is in other countries but in general in France you cannot just take a picture of a building and put it on Instagram without asking the architect for rights :

> the image of a building cannot be reproduced without the authorization of the architect who holds the copyright or of his successors in title. Otherwise, the reproduction of a protected work without the authorization of its author constitutes, according to the provisions of the article L122-4 of the Code of the intellectual property an act of counterfeit.
