The Sydney Opera House is one of the most recognizable buildings in the world, and its unique architecture has become a symbol of the city. The building's distinctive shell-shaped roofs are perhaps its most iconic feature, and they were designed to resemble the sails of a ship. The building is also notable for its use of natural light, with many of its interior spaces being designed to take advantage of the sun's movement throughout the day. The Opera House also features a number of innovative engineering solutions, including a massive concrete podium that supports the structure and a steel-and-glass "sail wall" that protects the interior from the elements.
