Mason's mark

Okay, so imagine you are building a really big, cool thing with blocks. Let's say it's a castle! Now, when you're building this castle, you want to make sure everyone knows who made it. So, you take a special tool and make a little symbol or picture on some of the blocks you use. This is like writing your name on your schoolwork or putting a sticker on your toy.

Well, grown-ups who build things, like big buildings and churches, do the same thing! They use a special tool to make a little symbol, picture, or letters on some of the bricks or stones they use in their work. This is called a mason's mark.

The mason's mark helps the person who made the building show off their work and it helps people who come after them see who built it. So, it's kind of like a secret code that only the builders know. Pretty neat, huh?
