Step into the heart of Turku's history at the Old Great Square, where you'll find the beautiful Cathedral School. As Finland's oldest school, its walls whisper tales from centuries past, standing proudly among other historic gems. While it's still a functioning high school, you can admire its stunning neoclassical architecture from the square, a place that buzzes with life, especially during the summer's Medieval Market and the magical Christmas Market. It's a perfect spot to soak in the city's medieval charm and capture a piece of Finnish heritage.
