1. The Hollywood Sign is an iconic landmark situated in the Hollywood Hills overlooking Los Angeles. It was originally created in 1923 as a real estate advertisement but has since become a symbol of the entertainment industry and the city itself. The sign measures 45 feet tall and is 352 feet long. It was constructed using steel and covered in flat white paint. Over the years, the sign has undergone a number of restorations and modifications to maintain its iconic appearance. Interestingly, the sign was originally intended to read \"Hollywoodland\" but the last four letters were removed in 1949.
