Where can you see Harry Potter, an England football match, a funfair and a Roman chariot all under one roof?
The answer is the Yorkshire Brick Show, an amazing collection of displays made out of Lego at York Racecourse.
Put on by Brickshire, the Yorkshire Lego user group, it is one of the largest annual displays of its kind in the country and has been running yesterday and today (Sunday, 16 April).
As these brilliant pictures and video by Gavin Aitchison show, there is something for everyone.
Trains zip around layouts, there’s an a steamboat with real steam, a farm and a massive animated funfair.
Visitors can bump into dinosaurs, Harry Potter and the Hogwarts Express, and a whole villa full of Romans.
The skill of the builders is so impressive. If you couldn’t make it, enjoy these pictures of a unique event.
