The best Lego we’ve ever built was the Harry Potter Hogwarts Castle. The castle comes with four huge rooms filled with secrets and surprises. With your characters Harry, Hermione, and much more you have endless adventures with the castle. It takes a long time to build, but it’s worth it. After it’s built, it’s still fun because you could spend hours making up new storys and games. And your friends would love to play with it too.
