Welcome to Castle Week!

Sixteen years of castles..

Leonardo’s Basement has been building castles almost since the Middle Ages. The first one was built from milk crates and eventually lumber and cardboard became the building materials of choice. Giant castles are great because many students can work on them, you can hide and do battle and they encourage physical work and play. During Castle Week students will not only build an amazing structure but they will make armor, costumes, food, decorations, a battering ram and catapults!

Best of all, after all the building we will have a celebration – Castle Fest – on Saturday, August 9 with food, music, games and performances. Mark your calendar!
