The Church of Colònia Güell (, ) is an unfinished work by Antoni Gaudí. It was built as a place of worship for the people on a hillside in a manufacturing suburb in Santa Coloma de Cervelló, near Barcelona (Catalonia, Spain). Colònia Güell was the brainchild of Count Eusebi de Güell; who enlisted the help of architect Antoni Gaudí in 1898. However, work was not started until 1908, 10 years after commission. The plan for the building consisted of constructing two naves, an upper and a lower, two towers, and one forty-meter-high central dome. In 1914, the Güell family halted construction due to the death of Count Güell. At the time, the lower nave was almost complete so between the years of 1915 and 1917, it was completed and readied for use. The Church is one of the seven properties Gaudí built near Barcelona that are Unesco World Heritage Sites. Collectively, these sites are known as the Works of Antoni Gaudí, and show his "exceptional creative contribution to the development of architecture and building technology in the late 19th and early 20th centuries." History At the age of 28, the Church of Colònia Güell was one of several commissions Gaudí received from Count Güell in the suburb of Santa Coloma de Cervelló. Planning To start the designing process of the church, Gaudí used his unique process of gravity and rope, known as a funicular system. As seen in the planning of La Sagrada Família, Gaudí hung hemp ropes attached to lead-filled sacks from the ceiling. By doing this, it allowed him to reproduce the curves of the church at a 1:10 scale. Gaudí also used canvas sheets to imitate the vaults and walls of the structure. By weighing down the ropes with lead-filled sacks, it allowed him to see the loads that would be exerted on the actual structure. To turn this hanging structure into his actual design, Gaudí photographed his model, flipped the image, and traced over it while adding some ornament and design. All that remains of the model for Church of Colònia Güell is an image in a book written by architect Josep Francesc Ràfols i Fontanals. This method of planning led to the development of a new architectural vocabulary, such as hyberbolic paraboloids and hyperboloids, which are prominent elements in many of Gaudi's designs. The Crypt The crypt portion of the church, constructed from 1908 to
