Like many of Willink's paintings, Château en Espagne was inspired by the metaphysical paintings of Giorgio de Chirico. The influence can be seen in its depiction of a mysteriously desolate building with classical architecture and distinct contrasts between light and darkness.[1] André Glavimans wrote in Elsevier's Geïllustreerd Maandschrift [nl] in 1940 that the heavy smoke in the horizon is reminiscent of Joachim Patinir's paintings and that this almost had become a cliché in Willink's works.[2]
Because of the title, the painting was understood at the time as a comment to the ongoing Spanish Civil War. Retrospectively it has been interpreted as anticipating World War II.[1] Glavimans interpreted its fiery motif as an anticipation of "the new and better world".[2] He described it as among Willink's more innovative paintings, which combines skilled painting, balance in the conception of the work, and an approach to classicism that creates a sense of simplicity, grandeur and familiarity.[2] According to Glavimans, this managed to create "a completely pictorial solution for the most intense inner tensions".[2] According to the description from Museum Arnhem, which owns the painting, the dark clouds connect the painting's elements and create a theme of contrast between life and death and wealth and decline.[1]
The Dutch writer Ferdinand Bordewijk based a prose poem on Château en Espagne. It was published in the book De korenharp in 1940 as "Châteaux en Espagne. Naar A.C. Willink".[3] The poem describes the painting, explicates a contrast between decay and harmony represented by the house and the statue, and mentions an approaching storm. In 2005, the literary scholar Mathijs Sanders connected these themes to the cultural pessimism of Oswald Spengler and Johan Huizinga, and to Menno ter Braak's defence of Willink as "an Apollonian painter, in whom the 'content' has been absorbed into the 'form', so that someone who unlawfully wants to separate the 'content' from the 'form' will only encounter emptiness and rhetoric".[3]
