Is it really closing, or is it just a rumor? (hoping for the latter)
Unfortunately the building is in a very poor state of repair and, in its current dilapidated state, it will cost an enormous amount of money to refurbish it.Why exactly is the aquarium being closed? Is it getting too expensive to run, or did the zoo decide the facility was outdated, or what?

I'm astonished that they have the nerve to put such a positive spin on the closure of the aquarium after nearly 100 years! I can see nothing positive about it and find it almost insulting that the advertising implies they are doing this through choice, not because they simply don't have the funds to renovate the aquarium !
Couldn't agree more - I've been a pretty consistent defender of ZSL on these forums over the years, but the fact that they couldn't simply be honest with the Fellows, at the very least, and say something like, 'With regret, we will be significantly reducing the collection of fish held by the Society as the Aquarium building at London is no longer fit for purpose, pending funds for its restoration' is just so contemptuous
As much as I'm in support of preserving the site's historic buildings, I honestly wouldn't mind seeing the Mappins knocked to the ground. They've done nothing but take up excessive space, rot and fall apart for the past decade (at least)! London Zoo is meant to be a zoo, not some kind of architecture display - it's just infuriating that they're getting rid of animals in favor of this.I look forward to see how they’ll (eventually) deal with the issue of the Mappin Terraces, because that’s one big can they can’t keep on kicking down the road for much longer!
