The first drawings of the chapel’s layout were created based on the suggestions of the Franciscan friar and historian, Capistrano. The plans were finalised by the son of Antal Lipthay, the architect Nicolás Lipthay Allen, who designed a concept based on the sketches and notes of his father. The project was then finetuned by the Hungarian architect Miklós Kovács adding to the concept form and spirit of the ancient Hungary of the Arpad dynasty, underscoring local traditions, and simplifying the construction. Miklós Kovács is also responsible for the supervision of the construction.
