Where was the lighthouse first used?

Answer 1

Electric illumination in the form of carbon arc lamps was first used, in a lighthouse, in Dungeness, on the South of England, England, in 1862.

From an excerpt of the official report dated December 1st, 1865

"In the light-room at Dungeness, there are two sets of optical apparatus, one the old reflectors formerly in use, which are kept always ready for being lighted in case of accident; and the other the dioptric apparatus for the electric light, which is placed in the upper part of the lantern. It was stated that since the establishment of this new method of illumination, the old reflectors have been occasionally used in consequence of accidents or from other causes, and on one occasion for a period of six hours."

Answer 2

The world's first known lighthouse, and the tallest, was built by the Egyptians somewhere around the year 279 or 283 BC. This was the famous Pharos, or lighthouse of Alexandria, which was situated on the eastern point of Pharos Island. Some believe that the Colossus of Rhodes was a lighthouse, but it was a war memorial, and never functioned as a lighthouse.

Answer 3

The Lighthouse of Alexandria, one of the seven wonders of the world, was the first ever lighthouse. It was built between 285 and 247 BC on Pharos island in Egypt. Getting the required resources to the island was extremely difficult, and the lighthouse was at the time the second tallest manmade structure in the world, after the Great Pyramid of Giza.
