This paper describes and analyzes three watercolors by the Valencian architect Manuel Cortina (1868-1950) titled Iglesia Parroquial (Parish Church) Casa de Recreo en una posesión de caza. (Country house in a private hunting preserve) and Fuente Monumental. (Monumental Fountain), focusing on the influence of C. N. Ledoux, O. Wagner and E. E. Viollet-le-Duc's drawings on Cortina s paintings. The paper also describes this transparent and distant painting method as emblematic of a period, the Belle Époque, and a movement the Vienna Sezession of the late 19th century, and its photographic, cinematographic and oneiric imagery.
