La Sagrada Familia in Barcelona, Spain, is renowned for its unique design by Antoni Gaudí. Having overseen the design work since 1883, Gaudí died in 1926, but the structure is still under construction under the hands of many architects and craftsmen. Ultimately, the completed cathedral will have a total of 18 towers : 4 bell towers representing the 12 Apostles (four bell towers on each of the three façades-Nativity, Passion, and Glory); the Tower of Jesus Christ (the tallest tower); the Tower of the Virgin Mary (the second tallest); and four other towers, dedicated to the four Evangelists, standing at the four corners of the Tower of Jesus Christ. La Sagrada Familia was designated a World Cultural Heritage Site in 2005. This 3D model paper craft shows how the La Sagrada Familia will look when completed.
