For thousands of years, humans have been building structures ranging from humble cottages to towering temples. Buildings mirror the environment around us and serve as a visual reflection of how it is always evolving. These structures are famous for a variety of reasons, including architectural appeal, historical relevance, and a fair blend of both: 

• Sydney Opera House, Australia – its unusual roof structure of shimmering white sail-shaped shells creates it one of the most recognizable structures in the world. That’s a spot to see the opera! 
• Leaning Tower of Pisa, Italy – the Tower, which was erected as a freestanding bell tower for the adjoining cathedral, is noteworthy for the shifting of its foundations, which led it to lean nearly 15 feet off the perpendicular. 
• La Sagrada Familia, Spain – is well-known for being one of the most recognisable instances of Antoni Gaudi’s distinct style, which combines aspects of Art Nouveau, Catalan Modernism, and Spanish Late Gothic design. It is the most recognisable emblem of Barcelona and the most visited landmark in Spain. 
• Petronas Towers, Malaysia – today, the 7th tallest building in the world. When it was completed in 1998, Petronas Buildings held the world record for tallest skyscraper. The towers were designed in a distinct post-modern style. Because steel was costly, the two 88-story buildings were mostly built with reinforced concrete. Its exterior is composed of glass and steel with Islamic art on it, reflecting Malaysia’s predominant religion. 
• Taj Mahal, India – it is a masterpiece of architectural style, with distinctive aesthetic characteristics in balance, symmetry, and harmonic blending of numerous parts. The Taj Mahal was erected by Shah Jahan as a tomb for his loving wife Mumtaz Mahal. The Taj Mahal is possibly the best example of Mughal art.
