To specifically cover the rules, there are two rules for this thread. First, the zoo or whatever it is called (safari park, aquarium wildlife park, game farm, etc.) has to be permanently closed, though it doesn't matter when it closed, it just has to be closed for good. Second and it cannot be a place which was replaced by another place of that type (such as a replacement zoo or aquarium) in the city area which opened within three years of its closing (i.e LA's Griffith Park Zoo wouldn't qualify because it was almost immediately replaced by the current LA Zoo which included the direct transfer of many animals.) I have seen a few mentions of Bristol Zoo on this thread, and that I will consider it okay because that replacement Bristol Zoo hasn't yet been opened yet.
EDIT: Can a moderator please edit this in with the first post of the thread?
