A masterpiece is often defined as the most remarkable work in an artist’s career, one which highlights the height of their techniques and ideals. The Mona Lisa by Leonardo da Vinci; Michelangelo’s Pietá; the Beatles’ Sgt. Pepper’s Lonely Hearts Club Band album. There are many examples, which are not always unanimously agreed upon. But what if what many consider to be the masterpiece was started by someone else, the credited creator didn’t live to see its completion, and almost all of its documentation was destroyed? Catalan architect Antoni Gaudí and his world-famous Temple Expiatori de la Sagrada Família are examples of these complications. From a highly crafted stone construction to the most modern 3D printing techniques and high strength concrete, numerous technologies were and continue to be incorporated in the project’s construction.
