A chimenea is something like a little fireplace that you can put on your porch or in your yard. It's made of clay or metal and has a long chimney that helps smoke go up and out of the way. You can light a fire inside the chimenea and use it to keep warm, roast marshmallows or hot dogs, or just enjoy watching the flames. But since it's a little different from a regular fireplace, it needs to be used carefully and supervised by a grown-up.
