The Sagrada Familia in Barcelona, Spain was designed by Antoni Gaudi with the floor plan of a Latin cross and Cubist design elements. Key features include the Passion, Glory and Nativity facades representing different aspects of Christ's life. Gaudi used light from stained glass windows and skylights to represent divinity, with different colors symbolizing theological concepts. Acoustics from the masonry construction create a holy echo, and organs are used for musical accompaniment during services.
