Including its islands, the country of Scotland has close to 12,000 miles of seashore, with 200 hundred lighthouses that act as beacons for all types of seafaring watercraft. These pharos come in an assortment of designs, as well as shapes and sizes. The North Queensferry Harbour Light Tower, situated below the northern expanse of the Forth Railway Bridge, measures just 23 feet in height, giving it the distinct honor of being the smallest lighthouse in the world.

It was designed in the early part of the 19th century by Robert Stevenson. Mr. Stevenson came from a long line of lighthouse architects, five generations to be exact. He also happened to be the grandfather of Robert Louis Stevenson, author of such nautical adventures as Treasure Island, Kidnapped, and Strange Case of Dr Jekyll and Mr Hyde.
