In the heart of the city of Castellón de la Plana stands the magnificent El Fadrí Tower—a free-standing bell tower that has become the main architectural symbol of this part of Spain. This monumental structure, standing approximately 58–60 meters tall, catches the eye with its unusual octagonal shape, a rare and exquisite example of Valencian Gothic with Renaissance elements.

The tower takes its name, which translates as "the bachelor," from its unique location: it stands separate from the Cathedral of Saint Mary for which it was intended. Architecturally, the building is divided into four distinct levels: a massive base, the main body, the bell chamber, and an elegant lantern spire crowning the structure.
Today, El Fadrí is more than just a historical monument; it is the living heart of the city's culture. Its belfry houses eight named bells, each with its own unique sound. The tower serves as a magnificent landmark for tourists and a point of pride for locals, recalling the region's rich medieval past.
