Oh goodness! I'm rather shocked... That's my local aquarium.It looks like the Weston Seaquarium is closing. I can't find anything on line but it was mentioned on the local news.
It must be prey unique as an animal attraction, occupying it's own pier.
I don't know who the owners are but there is another seaquarium in Rhyl
I've never heard of a Sea Life centre in Weston. The addresses you provide are the same so maybe there was a Sea Life on the site before it became Seaquarium.
Its probably a reasonable assumption that Weston was the same.
