What's the most amazing building you've ever seen - and why?
I went on holiday to Dubai and I saw an amazing building called Burj Khalifa - the tallest building in the world - and we went in it!

The most interesting building I've been to was St. Paul's Cathedral on a school trip. It was really cool because there is a whispering gallery where you whisper on the wall and people can hear you.
I think Beaumaris Castle on Anglesey is amazing! It's just like a maze inside... A-maze-ing!
Louis, Manchester, England
I saw the Shard when I went to London and I think it's amazing!

I went to the top of the Shard in London with my family. I like it because it is really high and you can see most of London from the top of it.

I saw a big department store in Birmingham. It's a big bubble. It looked pretty.
