This document describes a student project called "The Castle of Power" that aimed to help students understand the importance of history and cultural heritage. Students from Greece, Romania, Italy, Spain, and Turkey explored castles and walled cities, comparing traditions from different places. The project consisted of four sections represented by towers: the Tower of Friendship for collaboration, the Tower of Knowledge for learning about each other's histories, the Tower of Games for activities, and the Tower of Art for creative works. The goal was for students to learn about their shared cultural heritage across Europe and Turkey.
