Introduction to the Lighthouse of Alexandria: The Lighthouse of Alexandria was built around 270 BC in Alexandria, Egypt. It was the tallest building in the world at the time and was designed by the Greek architect Soschatus. For the next 1,500 years, the Lighthouse of Alexandria has been guiding sailors to the port in the dark night. It is also the last of the six wonders to disappear. The ratio of the lighthouse built in the park to its original shape is 1:2.
