Scholars estimate the Lighthouse of Alexandria measured between 383 and 450 feet high and was built in the third century B.C. to act as a landmark for Pharos, a small island off the coast of Alexandria, Egypt. The lighthouse's tower was built using light-colored stone, and at its highest point, a mirror was placed to reflect sunlight during the day; at night a fire burned to give off light. Some historians believe that the light given off could be seen for some 35 miles. The lighthouse was damaged by 2 earthquakes in 1303 and 1323, and its remains were destroyed in 1480, when a fort was built on the site.
I have discovered an awesome iPhone app called "Modern Wonders" - if you have an iPhone you should download it - if not your readers may be interested.
