An observation deck is a designated area, often located on the top of a building or structure, that provides visitors with a panoramic view of the surrounding landscape. These decks are commonly found in skyscrapers, towers, and natural formations, allowing people to enjoy scenic vistas and take photographs. Many observation decks feature amenities such as telescopes, informational displays, and seating areas. They are popular tourist attractions, with famous examples including the Empire State Building in New York City and the CN Tower in Toronto. Visitors often pay an entrance fee to access these elevated viewpoints.
