I was an Erasmus student in Brussels, so I ended up climbing the Gent belfry, partially climbing the one in Bruges, walking around the one in Tournai and snapping photos of those in Antwerp. Do I need to go to France to form my opinion of them? No, not really. For beguinage I saw I had 2-3 photos from the one in Bruges, but I don't remember it much and I am still not sure on how to 'see' it well. I still think I ticked it, I am not planning on going back. At the same time, I found a plate of 'Qanat of Zarch - Jennok Ab Anbar', saw the stairs, visited the Water Museum, but I don't think it's enough, so I don't count this one.
Then, I visited the monasteries in Bucovina on a school trip (I was 19, not really a kid) and I have no photos. I somehow remember that the church in Suceava had a green roof, but I googled it now and it is reddish. What do you do when your memory plays tricks on you?
