Wrought iron is a type of metal that was used a long time ago to make things like gates, fences, and other decorations. It's a very strong metal that doesn't bend easily, which is why it was so popular in the past.
Wrought iron is made by heating up iron and then hammering it to shape it. This process is called "forging," and it's kind of like how you play with Play-Doh to make different shapes. But instead of using your hands, you use big hammers and anvils (big metal blocks) to pound the hot iron into the right shape.
Because wrought iron is made by hand, each piece is unique and has its own character. It can be shaped into decorative swirls and curves, making it very pretty to look at. It's also very durable and can last a long time without rusting or breaking.
Nowadays, wrought iron isn't used as much as it used to be because it's expensive and takes a long time to make. But you can still see it in some fancy old buildings or homes, or even in antique shops.
