The Castle of Santa Florentina is an 11th-century medieval castle in Canet de Mar, Catalonia, Spain.
It was built on the foundations of an Ancient Roman villa by Guadimir de Canet. In the 16th century, it passed into the hands of Dimas Muntaner. In 1908, it hosted King Alfonso XIII, who made the castle's owner Ramon de Montaner i Vila count of Canet. In 1910, the castle was expanded and renovated by the modernist architect Lluís Domènech i Montaner, and its facade acquired some gargoyles by the sculptor Carles Flotats i Galtés. The magazine Architectural Digest covered the castle as among the "most beautiful houses in the world" in 1998 on account of its harmonious fusion of Gothic and Modernist designs.
