Walkthrough over the hippo exhibit

When was this hippo exhibit constructed? It used to be in a different place judging by pics.

@DelacoursLangur very late, but supposedly it was 2015

@felis silvestris Surprisingly poor zoo for such a wealthy microstate. I would love to see what they could do with the site with some proper investment. Its small, but unique and picturesque. The hippo exhibit is of a decent size as well, somewhat surprisingly.
