Presidio

Presidio is like a super important fort that helps protect a whole bunch of people and land. Just like you need walls and doors to keep your house safe from bad guys and monsters, a presidio has big walls and gates to keep enemies out. It's like a really big and strong clubhouse that soldiers hang out in to make sure everyone stays safe. They also keep important things like weapons and food inside to make sure people have what they need to survive. Think of it like a superhero headquarters that keeps everyone safe and happy!
