 Another architect of note is Felix Candela (Spanish), who designed the expressionistic church Nuestra Señora de los Milagros.This was a period of diverse experimentation and even structural innovation, as seen in the thin-shell concrete structures by the Spanish architect Felix Candela, such as his Church of the Miraculous Virgin (1953) in Mexico City and the Cosmic Rays Pavilion (1951) on the university campus.The integration of art and architecture became a constant in Mexican modern architecture, which can be seen in the courtyard of the Anthropology Museum (c. 1963–65) in Mexico City, by Pedro Ramírez Vázquez.
