HILLARY L.: Hi, I'm Hillary, and I'm standing in front of my local library. I'm going to talk to you about... columns!
Columns help keep up heavy structures like buildings and houses. In fact, in the ruins of ancient Greece, all that's left is the columns.
Columns are made out of compressing strong material like concrete, steel or wood. They come in all sorts of sizes. The top is the capital, the middle is the shaft, and the bottom is the base.
Sometimes they are hidden behind walls. And sometimes they're out in the open, like these. Or they can be used for decorative or monumental purposes. That's what I know about columns
