Perched majestically atop Monte Titano, this formidable tower is a testament to medieval craftsmanship. Constructed in the 11th century, it's the oldest of the trio and was initially used as a prison. With its sturdy stone walls and commanding position, it offers sweeping views of the surrounding countryside. Don't miss the intriguing collection of centuries-old artefacts housed within. Legend has it that in the past, its thick stone facade was considered impregnable. Wandering through its historic halls is like stepping back in time, a journey through age-old stories of defence and watchful peacekeeping.
