I've highlighted the four of these eight that I visited in 2017. I agree with you on Bratislava, but I wonder on what basis you chose to highlight the other three. Helsinki lacks many of the standard features of a zoo, such as an African savannah, great apes or elephants, and its tropical rainforest house is pretty lackluster. But it's nevertheless one that I would dearly love to return to, because it has a unique setting on an island in Helsinki's harbour. Attica Zoo isn't *beautiful* but it has a great collection and a high overall exhibit standard. Zagreb was one of the surprises of the trip for me, with one of the best collections of reptiles on the continent. I can't see on what basis you would argue against inclusion of any of them other than conventional wisdom being that they are not 'zoo nations'. edit: note that I wrote this without having gone back to page one, where I see you've included Helsinki and Attica in your first draft. You had it right the first time, I think.
