One of the attractions that I love at the Legoland is the Miniland. It is a model village which includes models of landmarks and scenes from around the world made from millions of genuine Lego bricks.
Here’s a picture of the miniature Treasure Island at the Miniland Las Vegas. The original one is found on the Las Vegas Strip.
No information is given as to how many lego bricks were used to recreate that popular hotel along the Las Vegas strip but I’m sure it’s composed of thousands of bricks and took a lot of time and effort to “construct.”
