In the later stages of his career, Dimitris Pikionis embraced a new commission, that of crafting a children's park. This endeavour provided him with an opportunity to revisit and expand upon the thematic elements he had skilfully employed in his design for the Acropolis. The Filothei park emerged as an embodiment of an analogous Arcadia, a realm where the interplay between nature and architecture remained intricately intertwined. Pikionis’s design sought to recapture a sense of unity that had been gradually eroded by the distractions of modernity. By integrating his signature Doric archaisms, he achieved a striking manifestation of the primaeval hut – a symbolically powerful element that transcends time and evokes the essence of human habitation in its most primitive form. Pikionis’s notion of an imagined Japan, depicted through a Mediterranean lens, further expanded the park's significance.
