So, imagine a big tower that's really tall and made out of wood or stone. It's kind of like a castle, but instead of people living in it, there are goats! Yes, real live goats.
The tower is built in a special way so that the goats can climb up and down it without falling or hurting themselves. There are little ledges and ramps for them to walk on, and sometimes there's even a spiral staircase inside the tower that the goats can use.
People sometimes build goat towers because they like to take care of goats and want to give them a fun place to live. Goats are really good at climbing things, so they love having a tower to play and climb on.
And the best part? When you look up at the tower, you'll see goats peering down at you from all different levels, almost like they're standing guard over their tower home. It's really cool!
