Castillo palacio de Cetina, Medieval palace and castle in Cetina, Spain

The Castillo Palacio de Cetina is a medieval palace and fortress stretching roughly 60 meters east to west, built primarily with masonry and brick. The structure features two towers at opposite ends and displays a clear division between fortified areas and residential sections.

The fortress was built in the late 13th century by King Peter III of Aragon as a defensive structure against the Kingdom of Castile. The building reflects the strategic importance of the region during medieval territorial conflicts.

The chapel occupies the north side of the main floor, and its ceiling takes the form of an inverted trough, not a barrel vault. The whole roof surface is covered with plasterwork (yeserías) that repeats heraldic and plant motifs, combining the vocabulary of Flamboyant Gothic with the Mudéjar practice of endless repetition. The doorway is framed in an alfiz, with a pointed arch above and a segmental arch below.

The site has different elevation levels with an eastern wing containing the original fortified areas and a western section with expanded residential spaces. Exploring both sections during a visit helps understand how the structure developed over time.

The writer Francisco de Quevedo married Esperanza de Mendoza in the palace chapel, though their marriage lasted only a brief time. This literary connection gives the location an unexpected cultural dimension.
