The Sagrada Família's interior, designed by Antoni Gaudí, uses a "forest" of tree-like columns that branch to support the roof and are made of different stones for strength. The history is reflected in its symbolic design, including 18 towers representing biblical figures, with the highest dedicated to Jesus Christ. Other interior features include the three entrances symbolizing Faith, Hope, and Charity, and stained-glass windows that change color to evoke different moods and times of day
