The Isabelline style, also called the Isabelline Gothic (Spanish: Gótico Isabelino), or Castilian late Gothic, was the dominant architectural style of the Crown of Castile during the reign of the Catholic Monarchs, Queen Isabella I of Castile and King Ferdinand II of Aragon in the late-15th century to early-16th century. The Frenchman Émile Bertaux named the style after Queen Isabella.[1][2]
It represents the transition between late Gothic and early Renaissance architecture, with original features and decorative influences of the Castilian tradition, the Flemish, the Mudéjar, and to a much lesser extent, Italian architecture. The consideration or not of the Isabelline as a Gothic or Renaissance style, or as an Eclectic style, or as a phase within a greater Plateresque generic, is a question debated by historians of art and unresolved.[3]
